I have been working on a lab assignment for class. The assignment is velocity analysis  and I have calculated omega and velocity values on a 8 bar link graphically and analytically. I have included a table that has the graphical results of the mechanism and wanted to make sure the analytical analysis is the same and also verify that the Matlab code that I put together matchs the results.
So, basically most of the work has been completed but I have mathematical errors in the code that may be related to the analytical analysis being incorrect. The code is a MatLab code m-file and has to answer the following questions. A. The code should find the values of the unknown parameters to confirm the graphical method results B. The code should plot the values of all the unknown parameters versus the input angles of 10.6 degrees and 60.03 degrees
