load multiple .dat files into matlab in matrix form

I have a folder of N .dat files that I want to load in matrix form. They all have the filename form B000XX.dat where XX are changing. How can I accomplish this please. This code is wrong but i know it should be along the lines of this.

 clear all
clc
importdata=['Cam_B_ds'];
for k=1:50
  importdata=[importdata dlmread(sprintf('B000xx.dat',k))]
end

You need to read the documentation of sprintf to learn how you actually specify how data is to be inserted:

sprintf('B000%02d.dat', k)

It is very likely that your

importdata = [importdata, dlmread(sprintf('B000%02d.dat', k))];  %Added a comma for clarity

will not do what you want but you haven't really explained what you intended to do with that line. And certainly, initialising importdata with a char array as in:

importdata = 'Cam_B_ds';  %brackets removed as they didn't anything except slow the code.

is certainly wrong. No idea what the intent is behind that.
