"by executing this command, you're eliminating any chance of using the PATH function later in your code"-not a problem I think; "Call LOAD with an output argument to obtain a struct array whose field names are the names of the variables from the file, and use dynamic field names (or regular field names, if you know the variables you want to access when you write the code) to extract the appropriate field"-did not understand very well. could you please give me a clear example please... I have changed slightly the code but still is not working: n_g=2; nb=conf; cd = pwd; for i =1 : n_g load([cd '\' nb num2str(i)]); end Any more suggestions or recomendations it will be helpfull.Regards

Look at the first bullet point in the "Troubleshooting: Loading Variables within a Function" section of this documentation page: http://www.mathworks.com/access/helpdesk/help/techdoc/import_export/braietb-1.html#bsdnp13 > I have changed slightly the code but still is not working: > > n_g=2; > nb=conf; > cd = pwd; Now you've locked yourself out from calling the CD function; and if this is a script file, whenever you try to change directory with this variable in the workspace you will (probably) receive an error -- you DEFINITELY won't change directory. > for i =1 : n_g > load([cd '\' nb num2str(i)]); > end > > Any more suggestions or recomendations it will be helpfull.Regards -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com |
