Linear Regression and Matrices
2007-10-19 04:59:00 So I know a good amount of math, more than the average guy on the street, but I love to learn new things. This week I passed out copies to the book Supercrunchers to my two kids in math club, and to get the ball started we went over how linear regression is calculated. I had no idea, and I found the following link that does a really great job, but it does almost the whole thing with matrices.

Some Operations on Matrix
2007-09-11 14:41:00 A few days back someone asked me a question via email which I thought might be useful to others too. So I’m listing that question along with its answer below. Q. I want to write a program such that users enter the value of matrix and each operation (listed below) is performed by functions. I want to use switch structure to call the functions. 1. Rotate the matrix around the diagonal. Example: 1 2 3 ---> 1 4 7 4 5 6 2 5 8 7 8 9 3 6 9 2. Rotate the matrix around the middle row. Example: 1 2 3 ---> 7 8 9 4 5 6 4 5 6 7 8 9 1 2 3 3. Rotate the matrix around the middle column. Example: 1 2 3 ---> 3 2 1 4 5 6 6 5 4 7 8 9 9 8 7 4. Set the upper triangle to zero. Example: 1 2 3 ---> 1 0 0 4 5 6 4 5 0 7 8 9 7 8 9 Ans. The following program does it. Please note that the matrix is declared as global so as to reduce complications in the program. Better way should have been to pass ...
Matrices
2007-08-19 20:14:00 Author: Denis SerrePaperback: 224 pagesPublisher: Springer; 1 edition (August 2002)Language: EnglishISBN: 0387954600(R)In this book, Denis Serre begins by providing a clean and concise introduction to the basic theory of matrices. He then goes on to give many interesting applications of matrices to different aspects of mathematics and also other areas of science and engineering. The book mixes together algebra, analysis, complexity theory and numerical analysis. As such, this book will provide many scientists, not just mathematicians, with a useful and reliable reference. It is intended for advanced undergraduate and graduate students with either applied or theoretical goals. This book is based on a course given by the author at the Ecole Normale Supérieure de Lyon. Denis Serre is Professor of Mathematics at Ecole Normale Supérieure de Lyon and a former member of the Institut Universaire de France. He is a member of numerous editorial boards and the author of Systems of Conser...
Merging Two-Dimensional Arrays (Matrices)
2007-07-16 11:54:00 In the article Merging One Dimensional Arrays, we discussed how to merge one-dimensional arrays, in this article we will be discussing about the merging of two-dimensional arrays. Merging as you know is the process of combining two similar things. In the context of arrays, it means to form a big array from two smaller arrays which has all the elements from both the arrays. In case of one-dimensional arrays there is only one way in which two arrays can be merged but in case of two-dimensional arrays there are two ways. Suppose, we have the following two 2d arrays (matrices): mat1={ {1, 2, 3}, {4, 5, 6}, {7, 8, 9} } and mat2={ {10, 11, 12}, {13, 14, 15}, {16, 17, 18} } then they can be merged in the following two ways: merge_row={ {1, 2, 3, 10, 11, 12}, {4, 5, 6, 13, 14, 15}, {7, 8, 9, 16, 17, 18} } merge_col={ {1, 2, 3}, {4, 5, 6}, {7, 8, ...

Algebra of Matrices (2D Arrays) Part II
2007-06-29 11:58:00 As you know from the previous article, matrices are 2D arrays. In the previous article, we saw how two matrices are added and subtracted. In this article, we will continue our discussion on algebra of two matrices by discussing how two matrices are multiplied. Multiplication of two Matrices Multiplication of two matrices mat1[a x b] and mat2[p x q] is only valid if b=p. While there are many algorithms by which two matrices can be multiplied, here I?ll give you the most simple algorithm. Others are used when efficiency matters. Algorithm for Multiplication of two Matrices Suppose, Two 2D arrays to be mat1 [p][p] and mat2 [p][p] having same number of rows and columns. A third 2D array, mul [p][p] to store the result. Here is the algorithm: FOR I = 0 TO (p-1) FOR J = 0 TO (p-1) mul [I][J] = 0 FOR K = 0 TO (p-1) mul [I][J] += (mat1 [I][K] * mat2 [K][J]) END OF INNER LOOP END OF OUTER LOOP Below is a example program which illustrates the multiplication of two ma...
Algebra of Matrices (2D Arrays)
2007-06-26 07:58:00 In the programming sense, Matrices are Two Dimensional or 2D arrays. Just as Matrices have rows and columns, similarly 2D arrays too have rows and columns. There are many mathematical operations like addition, subtraction, multiplication etc. which can be performed on matrices, and therefore to 2D arrays also. In this article, we will be discussing about the addition and subtraction of two 2D arrays (Matrices). Addition of two Matrices (2D arrays) For addition of two matrices both the matrices must have the same dimension. Ex. if matrice one has the dimension p x q then matrice two must have the dimension p x q. In the addition process, each of the element of the first matrice is added to the corresponding element of the second matrice and result is stored in the third matrice having the same dimension (i.e. p x q). Below is the algorithm for adding two matrices. Algorithm for adding two Matrices Suppose, Two 2D arrays to be mat1 [p][q] and mat2 [p][q] having p rows and q columns...
