MATLAB: Displaying a Matrix in Long Format

formatting

I have a matrix that is 5×3. I would like to display this matrix in long format, but I can't figure out how to do this.
disp(A) just displays 4 decimal points
Everything else I have tried is an error. Such as:
format long disp(A)
disp(format long (A))
etc.
I tried to accomplish this when building the matrix, too:
format long x = function(whatever)
A(i,j) = x
But this errors out too.
I'm at a loss. Can anyone help? Thanks.

try separating the 'format long' from the rest of your code perhaps this will help
format long;
>> rand(3,4)
ans =
   0.814723686393179   0.913375856139019   0.278498218867048   0.964888535199277
   0.905791937075619   0.632359246225410   0.546881519204984   0.157613081677548
