# How can I justify my matrices?

I know this might seem trivial, but I want to know how I can change how my matrices display, without functions. Is there a preference I need to change or something? I see other people have their matrices justified/aligned in the command window, but I can't seem to know why I don't. When working with lengthy matrices and symbolic variables this can become a hassle.
I show an example here of my output when working with Jacobian matrices.

There is no preference in MATLAB that is related to this.
The ragged display could happen if you had a variable-width font for the command window.

Thanks! This really helped! I changed the font to Consolas and it fixed it!

I find this form using Live Editor preferable to pretty.
syms t1 t2 t3 d3 a2
J11 = [-cos(t1)*(d3*cos(t2+t3) + a2*cos(t2)), sin(t1)*(d3*sin(t2+t3) +a2*sin(t2)), d3*sin(t2+t3)*sin(t1);
-sin(t1)*(d3*cos(t2+t3) + a2*cos(t2)), -cos(t1)*(d3*sin(t2+t3) + a2*sin(t2)), -d3*sin(t2+t3)*cos(t1);
0, d3*cos(t2+t3) + a2*cos(t2), d3*cos(t2+t3)]

It is certainly a nicer looking display.
Unfortunately the output is not something we can copy and paste into code (though pretty() is not suitable for code either.)
