I have two variables 'network' and 'sedsource'. I used the following code to produce the 'input' variable which contains 1 value for the common cells between the two variables and 0 for the others. Now i want to replace these 1 with the 'Volume' field values from the 'sedsource' variable such that the common cells have the volume values while the others are 0. Can anyone please help me with this?
Thank You
b = [network.FID_1];
a = [sedsource.FID_Networ];
Linknum = ismember(b,a);
Link=Linknum';
input = double(Link);

You can do as follows if you want to maintain it as struct array.
b = [network.FID_1];
a = [sedsource.FID_Networ];
[lib,loca] = ismember(b,a);
Vol = cell(size(network));
Vol(lib) = {sedsource(loca(lib)).Volume};
Vol(~lib) = {0};
[network.Volume] = Vol{:};
Alternatively convert your data into a table.
network = struct2table(network);
sedsource = struct2table(sedsource);
[lib,loca] = ismember(network.FID_1,sedsource.FID_Networ);
network.Volume = zeros(height(network),1);
network.Volume(lib) = sedsource.Volume(loca(lib));
