Week 2- 2R Robotic Arm Challenge

First i started the code by writing the inputs, the links length and the angles range for each link which start from zero to 180 degree counter clockwise with horizontal axis , then i put (ct) variable to use for plotting figures.

Then i used for loop and coordinates equations for plotting and in plotting commands i assigned a variable M to make an array of frames so matlab can use later to create video.

Then i have used these commands to create a movie.

The error i have face was in line 37 that wrote the word writer with small (w) and it should be with a capital (W).
