Remove first characters from a string
67 views (last 30 days)

I have a celll u(5,1) that looks like :
u{1,1}=''ART1/TEACH''
u{2,1}=''H0ME/SHOW''
I want to remove the first 5 characters from each of these strings so that :
u{1,1}=''TEACH''
u{2,1}=''SHOW''
How can I do it?

The duplicated single-quotes are not valid MATLAB syntax:
u{1,1} = ''ART1/TEACH''
u{2,1} = ''H0ME/SHOW''
Do you actually have a cell array of character vectors:
u = {'ART1/TEACH';'H0ME/SHOW'}
or a string array?:
u = ["ART1/TEACH";"H0ME/SHOW"];

... or if I understand "I want to remove the first 5 characters from each of these strings" literally
%%
u{1,1} = "ART1/TEACH";
u{2,1} = "H0ME/SHOW";
%%
for jj = 1 : size(u,1)
u{jj,1} = eraseBetween(u{jj,1},1,5);
end
It's recommended to keep strings in string arrays rather than cell arrays.
%%
u(1,1) = "ART1/TEACH";
u(2,1) = "H0ME/SHOW";
%%
u = eraseBetween( u, 1,5 );
inspect
>> u
u =
2×1 string array
"TEACH"
"SHOW"
And a final alternative
%%
u(1,1) = "ART1/TEACH";
u(2,1) = "H0ME/SHOW";
%%
u = extractAfter( u, "/" );
