I know how to properly multiply matrices, so that isn't the problem.

However, I'm working on a program that multiplies 2 dynamically created matrices, but the data is stored in one dimensional arrays. I thought it would be easier than creating an array of pointers that would point to arrays, but I can't figure out how to properly implement matrix multiplication on the 2 arrays.

In the followoing code, Matrix is a struct containing (int Row, int Col, and int *Data). Of course, this code doesn't multiply properly:

Code:

void matrixMultiply(int MatrixOne, int MatrixTwo)
{
cout << "Multiplying..." << endl;
int colCount = 0,
rowInc = 0,
colInc = 0,
Mat1Size = mList[MatrixOne].Row * mList[MatrixOne].Col,
Mat2Size = mList[MatrixTwo].Row * mList[MatrixTwo].Col;
Matrix Answer; //creates answer matrix
Answer.Row = mList[MatrixOne].Row;
Answer.Col = mList[MatrixTwo].Col;
Answer.Data = new int[Answer.Row*Answer.Col]; //allocates matrix space
for (int ii = 0; ii < Answer.Row*Answer.Col; ii++)
{
Answer.Data[ii] = 0; //initializes all data content to zero
}
for (int Count = 0; Count < Answer.Row*Answer.Col; Count++)
{
colCount = 0;
colInc = 0;
for (int rowCount = rowInc; rowCount < mList[MatrixOne].Row + rowInc; rowCount++)
{ //adding and multiplying rows/cols
if (rowCount > Mat1Size)
break;
Answer.Data[Count] += (mList[MatrixOne].Data[rowCount] * mList[MatrixTwo].Data[colCount]);
colCount += mList[MatrixTwo].Col;
if (colCount > Mat2Size)
{
colInc++;
colCount = colInc;
}
}
rowInc += mList[MatrixOne].Row;
}
matrixOutput(Answer);
}

Any help would be greatly appreciated.
