I want to calculate my 'poly' function for domain of linspace(0,1,100) so I tried ---------------------------------
%make poly function
function [output] = poly(input)
output= ([input^0 input^1 input^2 input^3 input^4 input^5]*transpose([1.0000 1.0001 0.4991 0.1703 0.0349 0.0139]) )
end
----------------------------------
x = linsapce(0,1,100)
poly(x)
----------------------------------
but it doesn't work. I found that for sin(x) it does. I want to know what's different between to func. and how to solve the problem.

What is the input you used? You have to take care of element by element operations.

function [output] = AsPolyvalForJaeSung(input)
output = bsxfun(@power,input(:),0:5)*[1.0000;1.0001;0.4991;0.1703;0.0349;0.0139];
end

For
input = linspace(0,1,100) ;
In the line
output= ([input.^0 input.^1 input.^2 input.^3 input.^4 input.^5]*transpose([1.0000 1.0001 0.4991 0.1703 0.0349 0.0139]) )
The size of term in square braces would be 1X600 where as the term transpose i.e second term got only 6X1 terms. How you expect them to multiply? You need to rethink on your code.
