How to remove a particular value (index) from an array? And also how to add a particular variable to an existing array?

hs(n) = {1,2,3,4} if i want to remove '3' from hs(n). What should i do? if i want to add '5' to hs(n). What should i do? Please use some variables to answer this ... Thanks in advance :)

Answer 1

[KSSV]

% if cell
hc = {1,2,3,4}  ;
hc{3} = 5 ;
% if matrix
hm = [1 2 3 4] ;
hm(3) = 5 ;

In terms of the original question,

hsn{n}(3) = 5;

I want to remove 'a' from hs(n). 'a' may be any one of the values from hs(n)

[KSSV]

Let i = 3 be the index you want to remove:

If cell:

    hc = {1,2,3,4}  ;
    hc{3} = [] ;
    hc(~cellfun('isempty',hc))

If matrix;

hc = [1 2 3 4] ;
hc(3) = []

Answer 2

[Walter Roberson]

mask = ismember(hs(n), 'a');
hs{n}(mask)  = [] ;

Note that the order of arguments for the ismember for this purpose is the opposite of what you might expect.

Also this code expects a cell array of strings, consistent with your use of '3' but not consistent with your initial assignment which had a cell array of numeric values. You used the string form more so I programmed for that.
