Error: ()-indexing must appear last in an index expression

I m getting this error while i try to execute this code

for i=1:n

    for j=1:n

        b1=bu(1,i)(j);
        a1=(n*b1/(m(i)*m(j)));
        p{1,i}=a1;

    end
end

here bu is a cell of size(1,n)

m is an array of size(1,n)

p is i a cell of size(1,n)

please help

Thanks in advance!

I'm guessing you want:

for i=1:n

    for j=1:n

        b1=bu{i}(j);
        a1=(n*b1/(m(i)*m(j)));
        p{i}=a1;

    end
end

This gives a new error Index exceeds matrix dimensions as bu is (1,n).

And we cannot access cell element this way.

bu is a cell and i can access it as

bu{i,j}

or

bu{i,j}(i or j)

[Walter Roberson]

b1 = bu{1,i}(j);

[Tripti Malviya]

This is what i did..

[Walter Roberson]

No, your code was

b1=bu(1,i)(j);

with round brackets after bu, not curly brackets. () compared to {}
