Create a MATLAB logo surface and perform the following.

$>$ L $=160*$ membrane $(1,100)$;

Suppose each cell size is $1$m $*1$m$.$

$1)$ Calculate the cut volume when cutting at an altitude of $100$m or more.

$2)$ Indicate the path from the mathematical coordinates $(201,201)$ or the image coordinates $($row $=1,$ col $=201)$ or L $(1,201)$ to the top, and calculate the average slope. $($Condition$)$ When moving from the starting point to the next cell, the slope change moves to the lowest point, but always moves in the upward direction
