not compatible with the size

itr=0; % number of iteration

for t=1:1:3

itr=itr+1;

b(itr)=[sin(t) cos(t)];

end

In the above code , I am getting the error " Unable to perform assignment because the indices on the left side are not compatible with the size of the right side."

Please tell me how to fix.

itr=0;       % number of iteration
for t=1:1:3
    itr=itr+1;
    b(itr, :)=[sin(t)  cos(t)];   % Two numbers for each iteration form a row for a matrix b (nitr x 2)
end
b

b = 3×2

itr=0; % number of iteration

for t=1:1:3

itr=itr+1;

b(itr, :)=[sin(t) cos(t)];

c(itr, :)=[1-sin(t) 1];

d(itr,:)=[b;c];

end

I get this error------Unable to perform assignment because the indices on the left side are not compatible with the size of the right side.

Please help
