Thread Subject:

batch re-nameing items in workspace

I have a bunch of structs in my workspace that I would like to rename by adding a tag onto the front of the struct name.

Something like:

old_x
old_y
old_z

new_x
new_y
new_z

I was looking for some way to use regular expressions to do this, but perhaps there is a better way. Any suggestions would be appreciated.

x = 'asfd'
y = 'asfdwerwe'
varNames = {'x','y'}
for i = 1:length(varNames)
  varName = varNames{i};
  assignin('base', ['new_' varName], evalin('base', varName))
end
