I want to join/combine these four png images but the codes are not working in R2017a

[KSSV]

the codes are not working..

why the codes are not working? What problem you sre getting?

[Joydeb Saha]

For the first code I am getting this error

Error using cat

Dimensions of matrices being concatenated are not consistent.

For the second code I am getting this error

Error using images.internal.getImageFromFile (line 7)

The specified filename is not a character vector.

Error in montage>getImagesFromFiles (line 355)

[img, map] = images.internal.getImageFromFile(fileNames{1});

Error in montage>parse_inputs (line 241)

[I,cmap] = getImagesFromFiles(varargin{1});

Error in montage (line 114)

[I,cmap,mSize,indices,displayRange,parent] = parse_inputs(varargin{:});
