I need to plot the content of a structure fiel:
Each row in the column Position is made by 2 elements (x and y). I need to plot all the rows at once on a scatter plot.
Using:
pop(1).Position(1)
I can access the first value of the first row/column. But I would like to plot all the column values without using a for loop.
Is that possible?
Thanks in advance!

Yes, in a way that is not apparent at first look, but very simple when you think about it:
[pop.Position]
I believe you can figure out the rest after this critical piece of information.

Its just:
[pop.Position]
Do that and check the answer. A simple reshape will solve your problem after that.

It worked with your suggestion plus buffer function:
a = [pop.Position];
b = buffer(a,2)';
Because using just [pop.Position] a get an 1xN vector. That's why it wasn't working.
Many thanks!
