I suck at delete

So it seems I don't know how to use delete properly in C++. I have a "Matrix" class that dynamically allocates memory for a 2D array of floats, and I'm creating and destroying tonnes of these as the application runs. So I put this in the destructor.


for(GLuint i = 0 ; i < height ; i++)
  delete matrix[i];

It crashes instantly.

Here is the matrix variable:

GLfloat **matrix;

And here is the code setting up the matrix:

matrix = new GLfloat*[height];
for(GLuint i = 0 ; i < height ; i++){
  matrix[i] = new GLfloat[width];
  for(GLuint j = 0 ; j < width ; j++){
    matrix[i][j] = (i == j && isIdentity ? 1 : 0 );
  }
}

Wtf is my stupid ass doing wrong?

I'm going to email GJS and ask for a picture of Julie and a brief outline of her contributions to SICP.
