Function: mat_cond (<M>, 1)
Function: mat_cond (<M>, inf) Return the <p>-norm matrix condition number of the matrix <m>. The allowed values for <p> are 1 and <inf>. This function uses the LU factorization to invert the matrix <m>. Thus the running time for
mat_cond is proportional to the cube of the matrix size;
lu_factor determines lower and upper bounds for the infinity norm condition number in time proportional to the square of the matrix size.
