Hi,

I am using a script to generate a plot/figure based on a numbers in text file. I am able to generate the figure, however, I would like to include a command at the end of the script for this output to be saved with the name "figure" in the same directory that the input was taken from. Any simple way to do this? (note--The input will be selected by hand every time via "spm_select").

The code is below:

rp = spm_load(spm_select);

figure;

subplot(2,1,1);plot(rp(:,1:3));

set(gca,'xlim',[0 size(rp,1)+1]);

subplot(2,1,2);plot(rp(:,4:6));

set(gca,'xlim',[0 size(rp,1)+1]);

Thanks!

Victoria

在 MATLAB Online 中打开

First, add a handle to the figure, then, use saveas:

rp = spm_load(spm_select);
h = figure;
subplot(2,1,1);plot(rp(:,1:3));
set(gca,'xlim',[0 size(rp,1)+1]);
subplot(2,1,2);plot(rp(:,4:6));
set(gca,'xlim',[0 size(rp,1)+1]);
my_saving_dir = 'C:\whatever'; % this is the folder to save to
my_file_name = 'file_name.fig'; % feel free to choose another extension
saving_name = strcat(my_saving_dir,my_file_name);
saveas(h,saving_name)

Thank you! That was very helpful and worked perfectly. Unfortunately now I am having trouble using this within a for-loop to handle multiple subjects at once--for some reason Matlab doesn't like the "saveas" within a loop, or the figure commands--but am much closer now.
