C: Is it possible to automatically create a given number of arrays?

Is it possible in anyway to recursively create a given number of arrays in C with predetermined length? I want to experiment with arrays for a clustering project and would be really practical if i could do this.

Yes it is possible, allocate an array of pointers then allocate all the arrays: 

T **array = malloc(rows * sizeof *array);

for (i = 0; i < rows; i++)
{
    array[i] = malloc(cols * sizeof **array);
}

it create rows numbers of array. Each array is an array of cols numbers of T.
