y=ax+b format,in  this y is of 20by 20 matrix
plot with respect to time
but the command window shows like below
pls help me to solve this
time span is
t=linspace(0,0.12,10)

Error using ==> plot
Vectors must be the same lengths.

size(t)
ans =

You can plot multiple columns of y with t, but t and y need to be the same length.
