A$1$ Using the header file Matrix.h and testMatrix.cpp $($given in the assignment folder$)$

Type the implementation file Matrix.cpp$.$

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

$\{$

row $N=1$;

ColN$=1$;

data$=$new float rowN $\{$:${?}^{**}$ColN$]$;

for $($int $i++$data$[i^{**}$colN$+j]=0$colN$=3N=3m(i,j)i**3+jj=0$;$ji=0$;$i$; $i++$
