my code returns a 200X200 matrix which has a structure in each of its element. Can I save/store it somewhere and load it later. The system seems to lose it when i close matlab. if i save the variable as .mat file in my workspace it cannnot bring it up later.

sure :)
ok my answer was kind of an overkill, sorry! let "a" be your 200x200 variable and "savea.mat" the file you want to save to. then the command that should do the job is
save('savea','a')
load('savea','a')
what i used above is the sprintf function that allowed me to save to dynamic file and foldernames. in this case sprintf had 3 arguments, "'%s\\%s\\filename'" ,"pwd" and "'foldername'". the first is a string that is interpreted where the %s places the content of the second an third argument in that position. pwd is a matlab command that returns the current matlab folder, let it be "C:\matlab". then:
foldername='fancyfolder'
save(sprintf('%s\\%s\\savea',pwd,'foldername'),'a');
should save the variable a into the file C:\matlab\fancyfolder\savea.mat note that you need the backslash and the "%" sign have special meaning within the sprintf function.
does this help?

I onec used
save(sprintf('%s\\%s\\filename',pwd,'foldername'),'varname');
load(sprintf('%s\\%s\\filename',pwd,'foldername'),'varname');
where pwd returns the current matlab workspace folder. if this does not help you i dont know :(
