MatLab question:

The vector x contains the side lengths for some unknown shape. If x contains 3 side lengths, then x represents a triangle. Moreover, if all the elements of x are equal, then x represents an equilateral triangle.

Using a series of if, elseif, and else statements, identify the most specific shape that x describes from the following:

triangle

equilateral triangle

quadrilateral

rhombus

polygon (for more than 4 sides)

n/a (for less than 3 sides)

Assign your answer as a string to the variable s.

Matlab functions all(), numel(), length() may be helpful.
