How do I use fprintf to print a matrix of MxM size where User chooses M

If user chooses M which is the size of the matrix and it is a MxM size. How would I fprintf that if M could be any real number?

I posted a simplified version of my code because its for a college assignment and I dont want to get expelled.

% -------------------------------------------------------------------- %

clear;clc;

sized = input('Enter value for matrix size (will be square ie. 2x2, 3x3 etc).   ');

randommatrix = rand(sized:sized)
randommatrix = round(randommatrix)


% I need to display the completed matrix to the command window
% this is what I have so far
fprintf('%d\n','       Final Matrix: ',randommatrix)

Some comments:

• note that sized:sized is just a more complex way of writing sized.
• using the colon operator to specify the size of the matrix is playing with fire (or more precisely, memory errors). Avoid.
• specifying the fprintf format as integer and then providing a character vector input is unlikely to do what you want (it will print the character values). To print a character vector/string you would need to use an appropriate format specifier, e.g. '%s'. In this case it is probably easier in a separate fprintf call.

>> N = 4;
>> M = randi([0,1],N,N);
>> F = [repmat(' %d',1,N),'\n'];
>> fprintf(F,M.')
 1 0 1 1
 1 1 1 1
 0 1 1 0
 1 0 1 1

This worked! Thank you! just one last question, how would I add a name to it also?

Like 'The Final Matrix Is: '

[matrix appears here]

fprintf('The Final Matrix is:\n');
