Thread: cant free my memory

hello ,i need some help with free memory
my allocation:
(pixel is struct of RGB)

Code:

pixel** array(int Y, int X) {
    pixel** theArray;
    theArray = (pixel**)malloc(Y * sizeof(pixel*));
    for (int i = 0; i < Y; i++) {
        theArray[i] = (pixel*)malloc(X * sizeof(pixel));
    }
    return theArray;

Code:

void freeMatrix(pixel ** pmatrix, size_t rows){            for (int i = 0; i < rows; ++i)
            {
                free((pmatrix)[i]);\\problem is here
            }
        free(pmatrix);
        pmatrix = NULL;
    }

what am i doing wrong ?
