Error using plot--vectors must be the same lengths?

Why am I getting the error message, "Error using plot Vectors must be the same lengths"? This code worked fine before I added a few more data points… Thank you in advance! :)

Side note: You should avoid naming a variable "load", because that is a MATLAB keyword.

[Not related to your present difficulty, most likely, but just good programming practice.]

Answer 1

[the cyclist]

This code ran to completion for me.

[Kelsey]

So you got the plot out?? I wonder why I'm not getting it… :(

Answer 2

[Joseph Cheng]

Plotted with mine as well. Kelsey can you tell us what dimensions (mxn) VertDisp and loadnorm are that you have in the work space?

Have you attempted to clear the workspace. Perhaps in your trouble shooting a dimension in either variable got screwed up.

[Kelsey]

They're all 52x1 matrices (vectors)! I removed the for loop, and now it works. How do I clear the workspace?

Thank you for your help!

[the cyclist]

Type "clear" at the command prompt.
