I'm not a big matlab fan. For a project I needed to apply a function for each element in an array. For that arrayfun can be used.
Here is a simple example.
Say you have 3 arrays as follows.
A = [1,2,3,4]
B = [5,6,7,8]
C = [9,10,11,12]
And you need to calculate the value of a function myf, for A[i], B[i] and C[i] (i=1,2,3,4) which returns A[i] x B[i] + C[i]
You can do it as follows.
First define your function considering a single element.
function output=myf(a,b,c)
output=a*b + c;
end
Then,
A = [1,2,3,4]
B = [5,6,7,8]
C = [9,10,11,12]
D = arrayfun(@myf,A,B,C)
Remember to have "@" before myf. It denotes a handle in matlab. If you forget it, matlab will try to evaluate the function instead of considering its handle, which may result in "Not enough input arguments" error.
