error with 20x10 array in a function

Hi;
Im having this error when i run "fcp" function (detailed below).
??? Attempted to access ASEB(1,1); index out of bounds because size(ASEB)=[0,0].
Error in ==> fcp at 15
Vsal(x)=ASEB(i,j);
Working out of the function, all variables load but it seems ASEB is not operating in the function.
Hope someone can help me
function [ Cp ] = fcp( beta,lambda )
%FCP Summary of this function goes here
% Detailed explanation goes here
global ASE
%ASE matrix loaded in workspace previously
ASEB=(0.0003*beta.^3 -0.0044*beta.^2 -0.0479*beta + 1.0850)*ASE;
x=0;
for i=1:20;
for j=1:10;
x=x+1;
Vsal(x)=ASEB(i,j);
end;
end;
%como el vector Vsal tambien se reduce en abcisas, habra que multiplicarlo
%de nuevo por otra funcion de B
fB2=(0.0026*beta.^2 -0.1031*beta + 1.2393);
Vsal=fB2*Vsal;
i=(200/20)*lambda;
fix(i);
Cp=Vsal(i);
end

Please format your code and you need to tell us the size of beta and lambda, give us some representative values.

Your ASE is matrix of what size?? Must be huge.. try to loop it...
r = size (ASE);
for i = 1:r(1) % 1:r(2) assuming it is column-vector.
values = Asme(:,1); %reads all values
ASEB=(0.0003*beta.^3 -0.0044*beta.^2 -0.0479*beta + 1.0850)* values;
output(i,:) = ASeb;
end
outputfilename = ['output\' outputfilename];
dlmwrite(outputfilename,output, '\t');
% now use this aseb for further calculations... I hope i got this question right. Since you are not looping over your values, it is storing only last set of data

function Cp = fcp( beta,lambda )
global ASE
Vsal = polyval(conv([0.0003,-0.0044,-0.0479,1.085],...
[0.0026,-0.1031,1.2393]), beta)*reshape(ASE',[],1);
Cp = [];
try
Cp = Vsal(fix(10*lambda));
catch
disp('Look size of ASE and value of lamda');
end
end
