How to make ternary plots in MATLAB

I was looking to make a ternary plot ( triangular). The conventional plot app in Matlab does not have an option for this plot. I was wondering if there's some code that could be passed , or if there is an app which exists which we could use for more convenient use.

There is no option for performing a ternary plot from within the plot app in MATLAB. 

However, here are a few file exchange submissions which I think you may find useful.

I've recently overhauled Ulrich's "7210-ternary-plots" to provide more support for customized ternary plots. See: https://www.mathworks.com/matlabcentral/fileexchange/93245-ternary_plots
