For this assignment you will turn in:
In class(10pts):
1. A statement of the problem (typed)
2. An explanation of your solution (typed)
3. A flowchart (hand-drawn or computer generated)
4. Pseudocode (typed)
Via BlackBoard(40pts):
1. C program named <username_matrix_mult.c
Assignment:
Follow the steps that we have outlined in class for algorithm development to generate a program that takes in two matrices (A and B) and multiplies them, then outputs the result. Remember matrix multiplication is NOT just C[0][0] = A[0][0]*B[0][0]. To multiply two matrices (A and B) together first, the number of columns in A must equal the number of rows in B. So A (4x2) x B (2x3) = C (4x3). Matrix multiplication works as follows:
11

× = ( ⋮

ℎ = ∑ ∗
=1
In short, you multiply each individual element of the row of A to the corresponding element of the column of B and then sum them.
Specifications:
Inputs:
- Dimensions of each array (n x m)
- The elements of each matrix (A and B)
Outputs:
- The resulting matrix C=A x B
Functions:
1. void printMatrix(int row, int col, float m[row][col])
a. prints a nicely formatted matrix
2. float calcEntry(float x[], float y[])
a. Takes the ith row of A and the jth column from B in order to calculate C[i][j]
b. Returns the value that will be put into C[i][j]
* This is the minimum functions that you must use. You may use others if you like.
Other:
1. This is individual work. You may NOT work in groups.
2. Please staple all work together.
3. You are expected to error check.
4. For code: No compile = No points, no exceptions!
