MATLAB: Converting a vector to matrix

matrix

I'm doing practice questions, and I am stuck. If the vector is x=[9,4,0,7] and i want to create a Matrix with 4 rows (the original vector, the recipricol, the factorial of the originals using my own code i already wrote, and the factorial using matlab's factorial function) while also putting ruler lines above and below the outputs. How the heck does one do this?

Not sure if this is what you are after, but it could be a starting point. Not sure what you mean by ruler lines above and below.

y=[x;1./x;factorial(x)];

MATLAB: How to tabulate this results using fprintf

Give some example values for your data...

Here is a generic example on how to make nice tabulations:

x = rand(5,1);
y = rand(5,1);
[r,t] = cart2pol(x,y);
fprintf('\n\n%11s%11s%11s%11s\n','x', 'y', 'r', 'theta');
fprintf(' %10.2f %10.2f %10.2f %10.2f\n',[x,y,r,t].');
fprintf('\n\n')

MATLAB: Using non number vectors and number vectors in the same fprintf command (beginner)

There is no good reason to do this in a single fprintf command, and the workaround necessary to do it would be painful. Do this:

fprintf('--------------------\n')
fprintf('%15.4f %15.4f %15.4f %15.4f\n', x',x2',x3',x4')

The reason this is hard is not that you are mixing numbers and text, but that you want a header line different from the rest. fprintf is not designed to do this. If the HW specifies you need it in one fprintf command, give us the exact wording and we may be able to figure out (hopefully) what they are actually asking for or at least why
