Problem $7$ Create a user$-$defined function that computes a ligament force value for Lecture $8-$ Problem $9.$ For the function name and arguments use $[$force$]=$ last$\_$name$\_$ligament$($l$\_$zero, l$\_$linear,slope,length$)$ From your homework file, call the user$-$defined function to compute force values for a range of ligament lengths between $20$ mm and $40$ mm$,$ every $1$ mm$.$ l$\_$zero$=25$ mm$,$ l$\_$linear$=30$ mm$,$ and slope$=100$ N$/$mm$.$ Follow these instructions: $$ Call the function inside of a for loop in your homework file using $20$ length $40.$ Remove the fprintf command from the program.
