Int res N N. For int a aBegin b bBegin.

How To Multiply Matrices Quick Easy Youtube

Then user is asked to enter two matrix and finally the output of two matrix is calculated and displayed.

Matrix multiplication result size. 24 28 22 48 4 32 36. Multiply mat1 mat2 res. Printf n.

My gpu is tesla c2070 cuda sdk version 42. Here are the steps for each entry. The main condition of matrix multiplication is that the number of columns of the 1st matrix must equal to the number of rows of the 2nd one.

The program below asks for the number of rows and columns of two matrices until the above condition is satisfied. For i 0. Int bStep BLOCK_SIZE wB.

Here is my code. Or more generally the matrix product has the same number of rows as matrix A and the same number of columns as matrix B. Abcdefgh aebgafbhcedgcfdh In this case we multiply a 2 2 matrix by a 2 2 matrix and we get a 2 2 matrix as the result.

Int aBegin wA BLOCK_SIZE by. A aStep b bStep __local float Ar_localBLOCK_SIZEBLOCK_SIZE. To store result.

They can be of any dimensions so long as the number of columns of the first matrix is equal to the number of rows of the second matrix. To multiply two matrices the number of columns of the first matrix should be equal to the number of rows of the second matrix. Int bBegin BLOCK_SIZE bx.

The column of first matrix should be equal to row of second matrix for multiplication. Matrix multiplication is not always defined When multiplying matrices the size of the two matrices involved determines whether or not the product will be defined. We then add the products.

If this condition is not satisfied then the size of matrix is again asked using while loop. This program asks the user to enter the size rows and columns of two matrices. Int aEnd aBegin wA - 1.

Printf Result matrix is n. J printf d res i j. For j 0.

Since we multiply the rows of matrix A by the columns of matrix B the resulting matrix C will have a size of 2 x 2. Int aStep BLOCK_SIZE. Multiply two matrices together.

For example if you multiply a matrix of n x k by k x m size youll get a new one of n x m dimension. The process is the same for any size matrix. Now the rules for matrix multiplication say that entry ij of matrix C is the dot product of row i in matrix A and column j in matrix B.

Recall that the size of a matrix is the number of rows by the number of columns. So i made code that perform matrix multiplication. You can also use the sizes to determine the result of multiplying the two matrices.

Version1 used global memory version2 used shared memory. It multiplies matrices of any size up to 10x10 2x2 3x3 4x4 etc. We can use this information to find every entry of matrix C.

As a result of multiplication you will get a new matrix that has the same quantity of rows as the 1st one has and the same quantity of columns as the 2nd one. We multiply across rows of the first matrix and down columns of the second matrix element by element. Define Matrix_Width 9216 define Matrix_Divide 4 define Tile_Width 32 define Ce_Size 4096 if Matrix_Width 9216 define Matrix_Size 92169216 elif Matrix_Width 12800 define Matrix_Size 1280012800 elif Matrix_Width 15872 define Matrix_Size 1587215872 elif Matrix.
