Remove first characters from a string

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"];

Answer 1

[per isakson]

... 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, "/" );

Perhaps try using cellfun in combination with extract?

u{1,1}="ART1/TEACH";
u{2,1}="H0ME/SHOW"

u = 2x1 cell array
    {["ART1/TEACH"]}
    {["H0ME/SHOW" ]}

f = @(x) extractAfter(x,5);
a=cellfun(f,u,'UniformOutput',false);
a=vertcat(a{:})

a = 2×1 string array
    "TEACH"
    "SHOW"
