Well, there is a number of ways.

You can delete the last character in a string. e.g. this way:

foo = bar(1:end-1);
.

You can use regular _expression_.

A couple of alternatives. These just show newline removal. Repeat for carriage return. For anything cleverer, you probably want regular expressions.

>s="123\n124"
s = 123
124
>s1=s
s1 = 123
124
>s1(s1=="\n")=[]
s1 = 123124
>s1=s
s1 = 123
124
>s1=strrep(s1,"\n","")
s1 = 123124
