hi
the issue is to make sure that this square matrix can be inverted - so how is this matrix generated ?

The error message tells you, that your matrix is near to be singular. Then it cannot be converted reliably, because the result is dominated by rounding errors.
This means, that there is a mathematical problem, which is not related to Matlab.
