How to replace the values in a variables based upon the common field values from another variable in matlab?

I have two variables 'P-idx' and 'Replacing_values'. P_idx is a bigger matrix consisiting of the FID_1 value/s from Replacing_values at different cells. Replacing_values has two fields: FID_1 and Volume. I want to replace the values of the FID_1 in the P_idx with the Volume values of Replacing_values based upon the common FID_1 values. Can anyone please help me how to do this?

Hi Niraj,

I believe you want to replace all the values in P_idx with their corresponding Volume(based on FID_1) values from the provided struct, please check the following code snippet:

non_empty_idx = find(~cellfun('isempty', P_idx)); % Finding all the non-empty indices
for i = 1:length(non_empty_idx) % Looping through the non_empty indices and replacing them with Volume
    P_idx{non_empty_idx(i)} = [network1(P_idx{non_empty_idx(i)}+1).Volume]; % Added 1 as FID_1 values started from 0 in network1
end

Hope this helps!
