MATLAB: How to print variables in command window with message

Question

A=[1, 3,4]

I want to print size of A is length(A) and A is print(A , length(A))

Answer 1

I had to make some guesses about exactly what you want output.

varname = 'A';
varlength = length(A);
fprintf('size of %s is %d\n', varname, varlength);
fprintf('%s is', varname);
fprintf(' %g', [A(:); varlength]);
fprintf('\n');
