arrays - Matlab: Return input value with the highest output from a custom function -

i have vector of numbers this:

myvec= [ 1 2 3 4 5 6 7 8 ...] 

and have custom function takes input of 1 number, performs algorithm , returns number.

cust(1)= 55, cust(2)= 497, cust(3)= 14, etc.  

i want able return number in first vector yielded highest outcome.

my current thought generate second vector, outcomevec, contains output custom function, , find index of vector has max(outcomevec), match index myvec. wondering, there more efficient way of doing this?

what described way it.

outcomevec = myfunc(myvec); [~,ndx] = max(outcomevec); myvec(ndx) % input produces max output 

another option loop. saves little memory, may slower.

maxoutputvalue = -inf; maxoutputndx = nan; ndx = 1:length(myvec)     output = myfunc(myvec(ndx));     if output > maxoutputvalue         maxoutputvalue = output;         maxoutputndx = ndx;     end end myvec(maxoutputndx) % input produces max output 

those pretty options.

you make fancy writing general purpose function takes in function handle , input array. method implement 1 of techniques above , return input value produces largest output.
