Plot Unit Vectors

Simple method to plot unit vectors in 3d

This function plots unitvectors X Y and Z or (e1, e2, e3) from an origin.
This function is fairly robust in that it can take 2 types of input. It can take a transformation matrix of the form
trMatrix = [1 0 0 0; pos' unitx' unity' unitz'] as:
fcn_plotUnitVectors(trMatrix).

Or it can take it as a combination of [1x3] vectors as:
fcn_plotUnitVectors(origin[1x3], csX[1x3], csY[1x3], csZ[1x3], vectorScale[1x1],colorSel)
colorSel can be a string used to format the vector as well.

The default coloring is
unit1 - red, unit2 - green, unit3 - blue

You can also set your own linestyles, for example:
if you have colorSel = ['''k'', ''LineWidth'', 5'] as the input, it will set the color to black and the thickness of the line to 5

Use: Easiest use is fcn_plotUnitVectors(trMatrix), however the vectorScale is not dynamic so it will need to be changed in the code if it doesn't suit your data.
