Error while running Matlab script for POD_DMD (error in mode)

Hello All,

I am using Matlab script POD_DMD for image visualisation. While runnig for 1D velocity visualization I am getting error.

Not enough input arguments.

Error in mode (line 58)

if isstring(x)

Error in POD_DMD (line 39)

imagesc(reshape(Phi(1:r*c,mode),r,c));axis

image;set(gca,'Ydir','Normal')

The code is added for your reference.

Please suggest possible solution for 1D velocity component.

Thanks
