Question 1

Matrix Determinant: 3x3 Matrices _hw8_1.c

Write a program that calls a function in order to compute the determinant of 3x3 array X. Finding the determinant involves expanding along a row or column and summing the weighted determinants of the sub-matrices obtained by omitting that particular row and column. For example, expanding along the top row and computing the determinants of the sub-matrices directly, we have that the determinant for 3x3 X as defined below is

Question 2

Matrix Multiplier: Matrices 3x3 _hw8_2.c

Write a program that calls a function in order to multiple 3x3 array X by 3x3 array Yand puts the result into 3x3 array Z such that Z=X*Y.

Matrix multiplication involves cross-products between rows and columns; written in summation form (maintaining consistency with the C numbering convention of starting from zero), we have that

Z(i,j)= X(i,k)*Y(k,j)

where and

All I/O is the be done in your main() function, which must then call a function to compute and return the matrix multiplication result. Hint: a triplet of for loops may be necessary in your function. Test your code with the following example:

X = and Y=
