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.

Ran in:
str = 'The quick brown fox jumped over the lazy dog';
unwanted = 'tixy';
str(~ismember(str, unwanted))
ans = 'The quck brown fo jumped over he laz dog'

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

s='picture' % Example
s(regexp(s,'[t,i,x,y]'))=[]

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