There are a variety of methods, and there are two more simple and practical. Method 1: File / Import Data ... / Next / Finish >> Whos Name Size BYTES CLASS

A4 =
'1111' '2222' '3333' '4444' '5555' is read in the form of a string, so there is ''.
Document content form 2 (assuming file name Test2.txt):

The following is a method written by chinamaker: fidin = fopen ('test2.txt');% Open TEST2.TXT file fidout = fopen ('mkmatlab.txt', 'W');% creates mkmatlab.txt file while ~ Feof (FIDIN)% judges whether it is the end of the file tLINE = FGETL (FIDIN);% from the file reads IF Double (TLINE (1))> = 48 && Double (TLINE (1)) <= 57% Judging whether the first character is value FPRINTF (FIDOUT, '% S / N / N', TLINE);% If it is a digital line, write this row data into file mkmatlab.txt continue% If it is non-number to continue the next loop Endendfclose (Fidout); mk = importdata (' Mkmatlab.txt ');% will import the generated mkmatlab.txt file into the workspace, the variable is named MK, in fact it does not display >> MK
