c program for matrix multiplication using 2d array
How to multiply two matrices using array in C?
Matrix Multiplication in C
1Step 1: Start.
2) Step 2: Declare matrix mat1[row1][col1]; and matrix mat2[row2][col2]; and matrix mul[row1][col2]; row= no.
3) Step 3: Read mat1[row1][col1] and mat2[row2][col2]4Step 4: Declare variable i=0, j=0.
5) Step 5: Set a loop from i=0 to i=row1.How do you multiply a matrix in an array?
Multiplication of two matrices is done by multiplying corresponding elements from the rows of the first matrix with the corresponding elements from the columns of the second matrix and then adding these products.
Note: The number of columns in the first matrix must be equal to the number of rows in the second matrix.1 août 2023To show how many rows and columns a matrix has we often write rows×columns.
When we do multiplication: The number of columns of the 1st matrix must equal the number of rows of the 2nd matrix.
And the result will have the same number of rows as the 1st matrix, and the same number of columns as the 2nd matrix.
What are the conditions for matrix multiplication in C?
Introduction to Matrix Multiplication in C
Two matrices can be multiplied only if the number of columns in the first matrix equals the number of rows in the second matrix.
The product of the two matrices will have the order of the number of rows in the first row and the number of columns in the second matrix.
