![The matrix_multiply() function receives two arrays of doubles representing two 2x2 matrices. It
then performs a matrix multiplication between the two matrices. The result of the matrix
multiplication should be stored in the first array passed.
The function must have the following function declaration:
void matrix_multiply (double matrixA[], double matrixB[]);
parameter
description
An array of 4 doubles, representing a 2x2 matrix. The result of the matrix
matrixA
multiplication is to be stored in this parameter.
An array of 4 doubles, representing a 2x2 matrix. This parameter is not to be
matrixB
modified.
The following illustrates how each array index correlates to the the matrix indices in our 2x2
matrix:
column 1
column 2
row 1
matrix[0]
matrix[1]
row 2
matrix[2]
matrix[3]
For example, the array {5, 6, 0, 3} represents the following matrix:](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F403d6ccc-1a09-48e2-8876-9543400565f5%2F9526413e-4808-401b-9900-a2f77999096c%2Fs9i0e06_processed.png&w=3840&q=75)
