Size of a function handle is not equal to YDATA

Hello, I declare a function and when I try to use the lsqcurvefit to this function the size is not correct. I get the error message "Function value and YDATA sizes are not equal". The size of the YDATA is [1 2049], the size of one of the parameters in the function is the same and the other parameter in the function is a scalar. Why does the size of the function change?

The most likely reason is that the data you are fitting are a row (column) vector, and the function is returning a column (row) vector, or other size discrepancies.
