Hi I have a collection of scenes on the name K in mupad. I can plot these scenes using plot::(K[1],K[2],..K[end]). I can plot individual scenes by calling through its index. Is there any way to plot all scenes using plot(K)..something like this??

                         Isthere any option called hold on as in MATLAB in mupad such that I can run loop and plot?
                        

Thanks in advance

Sreenu

I have not investigated plotting in MuPAD.

In Maple, plots are output as values with a particular structure that the pretty-printer recognizes and knows to draw. In Maple, you more or less join several plots together by just creating a list of the values and outputting that list, as in (Maple code)

                             P:= [seq]( 'plot(K[i])' $ i=1..nops(K) );
                            
                             plots[display](P);

Looking through the documentation, it appears that MuPad uses the same basic mechanism as Maple does. If your K is a list (not a Matrix or Vector) each element of which is a collection of graphic objects, then you can

plot(op(K))

since op() applied to a list results in an object sequence and functions are applied to object sequences.

If your K is an array or matrix or table, then

plot(seq('K[i]' $ i=1..N)

where N is the number of items in the array. Poking around it appears the easiest way to find the number of entries would be to use op() on the structured type to pull out the left and right sides of the index range stored in the object. Easier, perhaps, to coerce() the structured type in to a list.

Thank you very much.

This worked for me too.
