pdir='/Users/Phong/Desktop/RK4/'
load this
nameS=strcat(pdir,'InitCond30/','InitCond30_',int2str(run))
load(nameS);
it supposes to read /Users/Phong/Desktop/RK4/InitCond30/InitCond30_run
But it did not run that directory instead read the weird file and double letter like this
Error using load
Unable to read file
//UUsseerrss//PPhhoonngg//DDeesskkttoopp//RRKK44//IInniittCCoonndd3300//IInniittCCoonndd3300_ run:
No such file or directory.
Anybody has any idea why It reads and double the letter like that and how to fix it. Thanks

I generated the file in the folder InitCond30 with all run from 1 to 10
InitCond30 folder is located in /Users/Phong/Desktop/RK4/
It will create InitCond30_1, ....10
Now I want to load these files
pdir='/Users/Phong/Desktop/RK4/'
for run=1:10
if ic== 1
nameS=strcat(pdir,'InitCond30/','InitCond30_',int2str(run))
load(nameS);
end
end
The funny thing is they ran all from 1 to 9 and it did not run the last run 10.
[EDITED, Jan, code formatted - please do this by yourself, thanks!]

Loading directly to the workspace cab have unexpected results: What happens, if one of your MAT files contain a variable pdir? The result of the next iteration might be unexpected.
Therefore it is recommended to store the output of LOAD in a variable:
Data = load(nameS)
or Data{run} or whatever. Maybe this would solve your problem, but even if not, it is a good method to improve the quality of programs.
