Hi I'm trying to remove the whitespace around some surface plots I have made:

I have tried using linspace in both dimensions, but can only remove the white space on the x axis (appears as y axis on the image above as I've rotated the plot). My code is as follows:

amp_limits = linspace(first_amp, last_amp, num_amp);
term_limits = linspace(first_term, last_term, num_terms);
BER_mat = reshape(BER_single, num_terms, num_amp);
amp_mat = first_amp:amp_res:(last_amp-amp_res);
term_mat = first_term:2:last_term;
[amp_mat, term_mat] = meshgrid(amp_limits, term_limits);
%surface in 3D
figure;
surf(amp_mat, term_mat, BER_mat);
view(90,-90);
xlabel('Amp');
ylabel('term');

This removes the white space along the top of the image, but not on the sides. Why is this?

Thanks in advance.

See the axis function section on Set Axis Limits. You can set them to be whatever you want.

Thanks for the pointer. For completeness I've attached my working code below:

BER_mat = reshape(BER_single, num_terms, num_amp);
amp_mat = first_amp:amp_res:(last_amp-amp_res);
term_mat = first_term:1:(last_term/2)+0.5;
%surface in 3D
figure;
surf(amp_mat, term_mat, BER_mat);
view(90,-90);
xlabel('Amplitude (V_p_p)');
ylabel('Number of Fourier Terms');
title('BER plot');
axis([first_amp (last_amp-(amp_res)) first_term ((last_term/2)+0.5)]);
