The dis() function helps to display variables for debugging easily and conveniently.
Keeping track of changing variables during loops can be tedious sometimes. This simple function helps to produce a display variables in a simple and appealing manner with more functionality than Matlab's disp() function.
Usage:
a = 1; b = 2;
dis( a, b );
a = 1
b = 2

- Use '\n' to generate new line
dis( a, '\n', b );
a = 1

b = 2

- Use of varname
dis( 'value of a', a );
value of a = 1

- Display vectors:
x = (0:4) * pi/4;
dis( x );
x = 0 0.785398 1.5708 2.35619 3.14159

You can mix these features in the input randomly. Note that for calculations, indexed vectors and structs you will not see the input printed out literally.
