fevaln: feval with control of the order of the outputs
Syntax: [y1,...,yn] = fevaln(ind,f,x1,...,xn)
ind - Index of output to return or vector of indices to determine the order of outputs.
f - Function handle or function name.
x1,...,xn - Function arguments.
y1,...,yn - Output arguments returned in the desired order.
Examples from help:
Example 1: Find y coordinate of a point at x = pi that is 5 units away from the origin.
f = @(y) fevaln(2,'cart2pol',pi,y) - 5;
y = fzero(f,4)
Example 2: Create an anonymous function mysize that return dimensions of the input as [N,M] instead of [M,N].
mysize = @(x) fevaln([2,1],'size',x)
x = repmat(zeros(5,7),2,3);
[m1,n1] = size(x)
[n2,m2] = mysize(x)
arrayWidth = mysize(x)
