This is my code. It is functional, but whenever I run it, there is an error. I am stimulating the dart game cricket.
This is the error.
darts(17,19)
Index in position 1 exceeds array bounds (must not exceed 1).
Error in darts (line 22)

Your function call is darts(17,19), which means the wedges parameter passed into the function is the scalar 17, represented in MATLAB as a 1-by-1 matrix. Then, in line 22, you try to acccess wedges(xw,yw), where xw and yw are both random intergers in the range of [1, 512], and very likely both xw and yw are greater than 1, exceeding the size of the matrix wedges, and the error shows up.
