** Plot a function. **

** FPLOT(FNAME,LIMS) plots the function specified by the text variable **

** FNAME between the x-axis limits specified by LIMS = [XMIN XMAX]. **

** For example, FPLOT('sin',[0 10]) is a plot of the sine function. **

** FPLOT(FNAME,LIMS,N) plots the function with a minimum of N samples. **

** The default value for N is 25. **

** FPLOT(FNAME,LIMS,N, ANGLE ) plots the function with a minimum of N **

** samples and samples more if contiguous segments are at an angle **

** larger than ANGLE (in degrees). The default for ANGLE is 10 degrees. **

** FPLOT(FNAME,LIMS,N, ANGLE ,SUBDIV) plots the function with a minimum **

** of N samples, no more than ANGLE degrees bends in the curve, but no **

** more than SUBDIV iterations to fill in the rapidly changing portions. **

** The default for SUBDIV is 20. **

** [X,Y] = fplot(FNAME,LIMS,...) returns the abscissae and ordinates for **

** FNAME in the column vectors X and Y. Plot X versus Y to see the picture. **
