I have a question about a code. I have a string array and I would like to split it into pairs, depending the number of elements.

for example I have string 'CHARLES'. I would like to have a cell array with the elements C={CH, HA, AR, RL, LE, ES}. (I mean one cell array with 1x6 (length-1) dimensions)

my code is:

g='CHARLES'
length(g)
for i=1:(length(g)-1)
    C=horzcat(g(i),g(i+1))
    %charArray(i) = [AL(i){:}]
end

How must I modify my code? Could you please help me?

在 MATLAB Online 中打开

g='CHARLES';
C = cellstr([g(1:end-1); g(2:end)].').'
C = 1×6 cell array
    {'CH'}    {'HA'}    {'AR'}    {'RL'}    {'LE'}    {'ES'}

ok thank you @Voss. One more question. How could I use this command for a cell array?

I mean I have a cell array (2000x1 dimensions) and I want to use this command for each element of this array?

I write this code

for i=1:numel(g)
    C(i) = cellstr([g(i)(1:end-1); g(i)(2:end)].').'
end

but no use...

Could you pelase help me?

Use curly braces to access the content of cell arrays, not parentheses:

C = {'charles','hello','world'};
for k = 1:numel(C)
    C{k} = cellstr([C{k}(1:end-1); C{k}(2:end)].').';
end

Checking the content:

C{:}
ans = 1×6 cell array
    {'ch'}    {'ha'}    {'ar'}    {'rl'}    {'le'}    {'es'}
ans = 1×4 cell array
    {'he'}    {'el'}    {'ll'}    {'lo'}
ans = 1×4 cell array
    {'wo'}    {'or'}    {'rl'}    {'ld'}
