x=linspace(0,2.*pi,101)

plot(x,sin(x),'markeredgecolor','r',x,cos(x),'markeredgecolor','g',x,tan(x),'markeredgecolor','b',x,cot(x),'markeredgecolor','c',x,sec(x),'markeredgecolor','m',x,csc(x),'markeredgecolor','y','linewidth',1.5)

ylabel('Trigonometric Function')

xlabel('Angle (\theta)')

legend('southwest')

axis([0 2.*pi -5 5])

Error using plot
Invalid data argument.

You cannot put name-value pair arguments in the middle of data inputs. Either make these separate calls to plot (using hold on to put all the lines on the same axes) or call plot with an output argument and set the properties on the handles stored as elements of that output argument.
