How can I solve this error 'Unable to perform assignment because brace indexing is not supported for variables of this type.'?

Hi

this is my code

for i=1:448
g{i}=[0:1:447]';
end
    for i=1:448
U{i}=inv(K)*g{i};
        end

but it doesnot work for U and I recieved this error Unable to perform assignment because brace indexing is not supported for variables of this type.' can you help me with that?

You have not included enough of your code for us to debug this. You don't define K. If I do something simple, that gives K the correct size for a matrix multiplication:

K = rand(448);

for i=1:448
    g{i}=[0:1:447]';
end
for i=1:448
    U{i}=inv(K)*g{i};
end

then this code runs to completion.

Ideally post some self-contained code that we can run, that exhibits the error.

Thanks, K is an 448*448 matrix

OK, so I made a good guess by making up a random 448*448 matrix. But the code above does not give an error.

There is something else causing the error. Maybe you defined U as something other than a cell array, earlier in the code?

[talayeh tavangar]

yeah I have defines U as an other variable thanks for your help. How I want to use only element of (1,1) of each matrix that produce. can you help me with that?

[U, g] = deal(cell(448,1)); % before loops
