Combining 3 3D matrices

I have 3 3D matrices, which size are 313x409x31, 313x409x28 and 313x409x30. I would like to combine those 3 3D matrices into one 313x409x89. Pls help me.

Use cat:

 A=rand(313,409,31);
 B=rand(313,409,28);
 C=rand(313,409,30);
 total=cat(3,A,B,C);
 size(total)

ans = 1×3

313 409 89
