Hello everyone,
I would like to know how is it possible to use properly a viridis colormap in order to draw scatter figures. For instance, i have this figure to plot :
% plot(x1,y1,'^r','MarkerSize',8,'MarkerFaceColor',viridis(5))
But I don't know how to use this "alternative" colormap since I am not familiar with this function in this case.
Could someone help please ?
Thank you in advance.

See attached demos where I show you how you can replace the default color order of plots and markers with some custom colormap of your own creation.

Use scatter() instead of plot(). The behavior of viridis() is otherwise the same as the built-in functions like jet().
N = 20;
x1 = randn(N,1);
y1 = randn(N,1);

Yes you are right : I totally missed this argument. However, I am still unable to use this command since the viridis function is not recognized despite the fact that it's added to my current path. I don't understand why it doesn't work : I am going to check again for the path directory.

@Wissem-Eddine KHATLA: you can also place it into the current directory, which may be easier.
