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!
