Iterating through struct fieldnames in MATLAB

Question

My question is easily summarized as: \"Why does the following not work?\"

teststruct = struct(\'a\',3,\'b\',5,\'c\',9)

fields = fieldnames(teststru         


        

Answer 1

You can use the for each toolbox from http://www.mathworks.com/matlabcentral/fileexchange/48729-for-each.

>> signal
signal = 
sin: {{1x1x25 cell}  {1x1x25 cell}}
cos: {{1x1x25 cell}  {1x1x25 cell}}

>> each(fieldnames(signal))
ans = 
CellIterator with properties:

NumberOfIterations: 2.0000e+000

Usage:

for bridge = each(fieldnames(signal))
   signal.(bridge) = rand(10);
end

I like it very much. Credit of course go to Jeremy Hughes who developed the toolbox.
