![a) Type the implementation file Matrix.cpp, compile your files and get an application file.
Hint: the use of the float* data pointer for a matrix object can be understood with the help of the following empty
constructor function
Matrix::Matrix ()
// initialize Matrix class object with rowN=1, colN=1, and zero value
{
}
rowN=1;
colN=1;
data=new float [rowN*colN];
for (int i=0; i<rowN; i++)
for (int i=0; j<colN; j++)
data[i*colN+j]=0;
If colN=3 and rowN
m(i, j) will be data[i*3+j]
m(0,0), data [0*3+0]
m(1,0), data [1*3+0]
m (2,0), data [2+3+0]
m (0,1), data [0*3+1]
