Removing specific characters in a string?
显示 更早的评论
Im having difficulty in deleting pre-specified characters from any given string. The characters that i am tryin to eliminate are 't' 'i' 'x' 'y'
I need a lot of help creating a function that would do this for any given string.
for example
modstr('picture') should return ans = ('pcure')
or
modstr('alex') should return ans = ('ale')
I would appreciate any help or hints regarding this since i've been working on this for literally 6 hours now.
Thank You.

What about upper case characters?
str = 'The quick brown fox jumped over the lazy dog';
unwanted = 'tixy';
str(~ismember(str, unwanted))

str = 'The quick brown fox jumped over the lazy dog';
strn = regexprep(str,'[tixy]','')

This will replace commas too.

Consider
s == 't' | s == 'i' | s == 'x' | s == 'y'
