What's the script to have multiple msn's open?

Don't know whats wrong with my matlab script?

• x = [ 1 2 3 4 5] y = [ 3 5 6 9 2] plotcolor = input('What type of color do you want (r(red) b(blue) or g(green)): ','s'); plottype = input('What type of plot style would you like(cirlce(o) or star(*)): ','s'); pstr = sprintf('%s%s',plotcolor,plottype') plot(x,y,'pstr') the problem is to create a script that will create x and y vectors. then the script will ask the user for a color and for a plot style. it will then create a string pstr that contains the color and plot style, so tat the call to the plot function be plot(x,y,pstr). For example, if the user enter 'blue' and star(*), the variable pstr would contain 'b*' I feel like i have done this exactly but i keep getting an error that reads ??? Undefined function or variable 's'. Error in ==> length at 2 area = sqrt(s*(s-a)*(s-b)*(s-c)); Error in ==> cla at 19 if nargin>0 && length(varargin{1})==1 && ishghandle(varargin{1}) && strcmpi((get(varargin{1},'Type')),'axe… Error in ==> newplot>ObserveAxesNextPlot at 125 cla(ax, 'reset',hsave); Error in ==> newplot at 74 ax = ObserveAxesNextPlot(ax, hsave); Error in ==> peterpan at 6 plot(x,y,'r*')

• Answer:

  I do not receive the same error as you. However the one thing I see wrong in your script is that you call: plot(x,y,'pstr') A working script for me is: x = [ 1 2 3 4 5]; y = [ 3 5 6 9 2]; plotcolor = input('What type of color do you want (r(red) b(blue) or g(green)): ','s'); plottype = input('What type of plot style would you like(cirlce(o) or star(*)): ','s'); pstr = sprintf('%s%s',plotcolor,plottype); plot(x,y,pstr); The plot function will try to evaluate 'pstr' as a string and not the variable if you use it in quotes. The values 'pstr' are not valid arguments in the color/linetype argument for plot. If you still are receiving errors, try to delete all the variables in your workspace and clean up your script file.
