Coordinates In workspace to x1 y1 ,x2 y2

I have a variable X= [3,2,4,5] , Y=[5,3,3,6] , similarly many other in my workspace. How do I plot these variables individually. I am using a list box in which all these variables are listed. To plot line X the coordinates would be x1=3, y1=2 ,x2=4 ,y2=5, so how can i convert the 4 element vector(X,Y,..) into a x1,y1,x2,y2 format . thanx in advance

What do you hope to achieve by having lots of separate variables? Have you tried plotting the vectors? What does this do that you do not want? Please explain why you need separate variables to plot.

[Stephen23]

It seems that you do not use the Y values at all, only the X values:

x1=3, y1=2 ,x2=4 ,y2=5 <- these seem to be the X values

So where are the Y values used? Can you please explain the task with complete input and output data.

The user has a number of four-element vectors, and wants a way to break each four-element vector into variables x1, y1, x2, y2.

I have to plot those vector lines individually after they are listed in listbox , when i click on them the line gets plotted. So X,Y.. and many other four element vectors are listed in my listbox, when i click on any one of them and then click plot. the vector should get plotted. But I cannot convert the four elements of vector into x1,y1 & x2,y2 from my workspace, where they are saved as an array for ex:- X[1,2,3,4]

[Walter Roberson]

Are they listed by variable name or by content of the variables in the list box? How are you converting the list box selection into the appropriate content?

[Himanshu Tomar]

The workspace variables are listed in the listbox. I can just set the selection of variable selected in the listbox and then while plotting i want to plot the 4 elements as x1,y1 and x2,y2. How can I do that

[Walter Roberson]

I need to see the code that sets the String property of your listbox, and I need to see whatever code uses the Value property of your listbox to decide what is being done.

Answer 1

[Walter Roberson]

x1 = Variable(1);
y1 = Variable(2);
x2 = Variable(3);
y2 = Variable(4);

Or

Variable_cell = num2cell(Variable);
[x1, y1, x2, y2] = Variable_cell{:};

Now if the point was to plot the variables then

plot(Variable([1 3]), Variable([2 4]))

with no need to break it into x1/y1/x2/y2

[Stephen23]

plot(Variable([1 3]), Variable([2 4]))

is the best solution.
