MATLAB: Detect P-code

deploymentdiagnosticsMATLABpcode

Is there a way for a function to query if it is running from an m-file or if it has been deployed as a p-file. The function "isdeployed()" returns zero for p-code. Is there anything equivalent to "ispcode()"?

Thanks

Ronan

Maybe this:

a=dbstack('-completenames');
if (isempty(strfind(a.file,'.m')))
disp('pcode')
else
disp('mfile')    
end

Hi!

count = 1;
tline = fgetl(fid01);
while ischar(tline)
count = count + 1;
disp(tline)
if count == 3
fprintf(fid02,'%s\r\n',tline);
end
tline = fgetl(fid01);
end 
fclose(fid01);
fclose(fid02);

You can do as well

for n = 1:3
tline = fgetl(fid01);
end
fprintf(fid02,'%s\r\n',tline);
fclose(fid01);
fclose(fid02);

MATLAB: Are P-files creating problems with different MATLAB releases

This change has been incorporated into the documentation in Release 2010b (R2010b). For previous releases, read below for any additional information:

The process of the decrypted intermediate MATLAB code format has changed in MATLAB 7.6 (R2008a). Therefore, a P-file generated in MATLAB 7.6 (R2008a) or later will not run in older releases.

To avoid this issue, use the same version of MATLAB for generation and execution of a p-code file.
