options = optimset('Display', 'off') isn't working. fminsearch is still printing out values

Hi all,

I am running fminsearch on a function that is optimizing the vector, weights_vector. The vector gets optimized for each day, and is stored as a column in a big weights_matrix

options = optimset('Display', 'off');
weights_matrix = ones(num_rows, num_dates);
for d1=1:num_dates
  %this workspace variable 'value' is passed to fun, which is minimized by iterating over weights_vector
  assignin('base', 'value', value_vector(:,di));
  weights_matrix(:, di) = fminsearch(@fun, weights_vector, options);
end

After running this in the command window, MATLAB keeps printing out iterations (scalar values) of fminsearch, even though I set the options to off via optimset. What's going on?

I don't think you posted the whole code. I don't have any problems.

Could we see the code of "fun" ?
