@jan simon equations are working well for me, when i am trying to plot its show too input aruguments

 plot(xa,ya)
  plot(xb,yb)
 plot(xc,yc)
 plot(xd,yd)

[José-Luis]

Could you please post the error message.

[José-Luis]

And the output of

 which plot

is?

Your code works for me. I just put it into a file and commented out the "clear all" and "clc" (because those have no business being inside programs; If I wanted to clear the screen I would clear the screen!) .

I suspect that somewhere on your path you have your own plot.m routine. What shows up if you use

which plot

Equations are Working for me, I can't able to plot my grah

Please show the output of

Error using plot Too many input arguments.

Error in my_code (line 68) plot(xa,ya)

[Walter Roberson]

At the command line, give the command

which plot

and tell us the result.
