How to loop through cell array and apply script to each double?

Question

0 个投票

Hi,

I have a cell array of cell arrays of doubles called "C_512_numeric". I have the script called edit and I want to loop through all columns in the doubles in C_512_numeric and use the column data as input for edit (first argument). I have attached the script.

How would I write this code?

You can use the cellfun function, where you use your script as the function. Example:

a = {1:3, 200:205, 10:12};
new_a = cellfun(@(x) myfun(x) ,a,'UniformOutput',false);
new_a{:}
ans = 1x3
    -2    -4    -6
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
ans = 1x6
  -400  -402  -404  -406  -408  -410
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
ans = 1x3
   -20   -22   -24
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
function y = myfun(x)
y = x*(-2);
end

I dont think I quite understand. I am not that familiar with cellfun. Could you kindly show me the script?

The script is within the answer already. What exactly is the part you are struggling with?
