Programming

I ran degugger in C++ and the followings are the message I got:

I am not sure where the problem is. I would guess it's from matrix.h, so I attached that part of the program.

template<class T> inline Matrix<T>& Matrix<T>::resize(const size_type m,const size_type n,const T& val)
{
if (m == 0 || n == 0) {
clear();
} else {
int i,j;
if (m != nrow || n != ncol) {
clear();
nrow = m;
ncol = n;
me = new T* [nrow];
assert( me != 0 );
for (i=0; i<nrow; ++i) {
me[i] = new T [ncol]; // line 286
assert( me[i] != 0 );
}
}
for (i=0; i<nrow; ++i) for (j=0; j<ncol; ++j) me[i][j] = val;
}
return *this;
}

Could somebody educate me what the problem is?

Thank you so much.

These memory problems can be hard to pin down. Unless your system is actually running out of memory, quite unlikely, the problem likely occurs earlier, with an invalid free.
