MATLAB: Operation using *.m file

math function

Can we make mathematical operation by calling our *.m function? For example, I have hthresh.m and sthresh.m. I want to get the average value of these 2 file.

Best Answer

make hthresh.m and sthresh.m as function files

function val1  = hthresh()
function val2 = sthresh()

and use the below code in another .m file

val1 = hthresh();
val2 = sthresh();
avg = (val1+val2)/2;

k should span from 1 to size(IDHMA,2), similar to ii:

for ii = 1: size (IDHMA,1)
for kk = 1 : size (IDHMA,2)
   IDHMAlog (ii,kk) = log(IDHMA(ii,kk))
   if IDHMA(ii,kk) == 0
       IDHMAlog(ii,kk) = NaN %exclude the"-Inf" values
   else 
       IDHMAlog (ii,kk) = log(IDHMA(ii,kk))
   end
end
end

I believe you could avoid the loops if you'd like:

IDHMAlog = log(IDHMA);
IDHMAlog(IDHMA==0) = NaN;
