Hi everyone
I have a problem with the code below, in this code i want to write some equations. The problem with defining mu1 how can ii define it, i am new in matlab and i cannot define it.
for i=1:200
for j = 1:9
y{i,j}= CensoredGaussian(mu1(i,j),psi1(j),thd(j,z1(i,j)),thd(j,z1(i,j)+1));
end
mu1{i,1}= {mu.y1(1)+xi1(i,1)};
mu1{i,2}= {mu.y1(2)+lam1(1)*xi1(i,1)};
mu1{i,3}= {mu.y1(3)+lam1(2)*xi1(i,1)};
mu1{i,4}= {mu.y1(4)+lam1(3)*xi1(i,1)};
end
The error is ??? Undefined function or method 'mu1' for input arguments of type 'double'.
Any help would be highly appreciated. many thanks in advance

Add Following code at first line. This will construct a cell array..
mu1 = cell(10,10);
c = cell(m, n) or c = cell([m, n]) creates an m-by-n cell array of empty matrices. Arguments m and n must be scalars.

Add
mu1 = cell( 200, 4 );
before the for-loops and read Preallocate Memory for a Cell Array
Next replace
mu1{i,1}= {mu.y1(1)+xi1(i,1)};
by
mu1(i,1)= {mu.y1(1)+xi1(i,1)};
etc. to do what I believe you intended. And read Access Data in a Cell Array
Finally, I would like to ask, why do you use cell arrays in the first place.

Thank you very much for your response. I have now a problem here
for j = 1:9
y1{i,j}= CensoredGaussian(mu1(i,j),psi1(j),thd(j,z1(i,j)),thd(j,z1(i,j)+1));
end
the problem is
??? Error using ==> subsindex
Function 'subsindex' is not defined for values of class 'cell'.
how can i define subsindex using cell
many thanks again
