cellfun usage trouble
显示 更早的评论
I am having trouble using cellfun in a specific case.
For example I have the following code:
prefix={'IS','MI'};
IS_max = 5;
MI_max = 6;
If I run
eval([prefix{1},'_max'])
I get the expected result, 5.
If I run
cellfun(@(x) eval([x,'_max']),prefix)
I get an error that IS_max is undefined.
Any suggestions for how I can get the cellfun command to work? My desired output would be [5,6];
thanks very much,
-Brian

You cannot do that. http://www.mathworks.co.uk/support/tech-notes/1100/1103.html

Try evalin instead, which forces the function to reference the base workspace (rather than the local one):
cellfun(@(x) evalin('base', [x,'_max']),prefix)

Using eval or evalin to access variables is prone to errors, hard to debug and in reduces the speed substantially. This topic has been discussed repeatedly in this forum and a search is recommended.
