We want to make a text line into a function with variable length according to the situation:

functext = '';
for nt =1:N, 
    functext = sprintf('%s @(c,xdata) sin(c(%d)*xdata+c(%d))',functext,1+2*(nt-1),2*nt);
end

This is to form a funlist with structure as:

funlist = {1, @(c,xdata) sin(c(1)*xdata+c(2)), @(c,xdata) sin(c(3)*xdata+c(4)), @(c,xdata) sin(c(5)*xdata+c(6)) ... };

for use with a very good tool "fminspleas" from "matlab-file-exchange" with a linear summation of a series sinusoidal functions:

y = a0 + a1*sin(c1*x+c2) + a2*sin(c3*x+c4) + a3*sin(c5*x+c6) + ...;

How to convert the functext into funlist? eval? str2fun?

Thanks.

The function referred to is this one from John D'Errico:
