Thread Subject: strip line feeds, white spaces, control character

I need to remove 1)line feeds) white space and blank spaces
3) any control character from my text file (abc.txt).
I tried using 'deblank' and 'strtrim' but not much success.
Any suggestions?

abc.txt

/se/j1_en = OFF
/se/j1_ag_en = ON
/abc/j1_xyz/f0 = 0.000170
/abc/j1_xyz/f1 = 1.001234
/abc/j1_xyz/f2 = -1.234567
/abc/j2_xyz/f0 = 0.939140
/abc/j2_xyz/f1 = -0.966763

Hi,

Here is one of the solutions. Once you have read the text
string s, do this:

indx = find(s==char(13) | s==char(10) | s==' ');
s(indx) = [];

This offers an approach:

s = textread('abc.txt','%s')
LongString = cat(2,s{:}) ;

You could use regexprep in between to remove certain
character sequences, like in

s = regexprep(s,'(/abc)','')
