How to display the filename correctly?

12 views (last 30 days)
I am trying to export a figure with a file name that is derived from the string name after a section of a code. Below is the export fig part. But for some reason, instead of printing the actual name of string the code prints fig_name as the file name. What can be done to avoid this?
p1 = strfind(fname,'.csv');
fig_name = string(fname(1:1:p1-1));
fig_name = sprintf(fig_name + '.png')
%% export the figure
export_fig fig_name -transparent

You are using the command format of export_fig. MATLAB does not understand fig_name is used to refer a variable and just consider it as a string. Use the functional format
export_fig(fig_name, '-transparent')
