"patch" command error

I have two matrices one with vertices-(280×3) and the other one with faces-(556×3) .
Using patch command as follows
P=patch('Faces',f11,'Vertices',k1); %%%%%f11= face matrix and k1=vertex matrix.
set(P,'FaceColor','b','FaceAlpha',0.5);
set(P,'EdgeColor','k','LineWidth',2);
It gives the following error
Error using patch
Value must be of numeric type and greater than 1
Attached are the two files containing the matrices.
Any suggestions on how to eliminate this problem
Thanks.

I suspect you generated the vertex IDs in a programming language that is zero-indexed, instead of one-indexed. If that is the case you can probably fix the issue like this:
P=patch('Faces',1+f11,'Vertices',k1); %%%%%f11= face matrix and k1=vertex matrix.
set(P,'FaceColor','b','FaceAlpha',0.5);
set(P,'EdgeColor','k','LineWidth',2);

You're welcome.
I assumed they weren't generated by Matlab, and most other programming languages are zero indexed. So it was an educated guess. And generally the first few faces will contain the first vertex, but in the txt there were a few zeros where I expected ones.
