How to perform non linear regression on a multiple input multiple output matrix equation?

Let's say I have the following matrix equation (where X is my input vector, Y is my output vector and B is my vector of parameters to be estimated):

If I have a 100x3 data matrix for X and a 100x2 data matrix for Y, how can I perform non linear regression to estimate the values of B(1), B(2) and B(3)?

To the best of my knowledge, the function 'nlinfit' requires that Y be a column vector.

For anyone who is also wondering about the same question, I was able to find the solution by searching around a bit.

'lsqcurvefit' is a MATLAB function that solves this problem.
