Get new variable if a cell in a column changes - Matlab

I have a cell-type variable X and I would like to have variable X separated in different variables for each different Firm (X(:,1). Meaning, everytime Firm name changes I get a new variable. Example:

X:

Firm 
'ABC'  0,5  46  19970224
'ABC'  0,6  29  19970424
'EFD'  0,5  145  19970218
'EFD'  0,5  36  19970206
'GHI'  0,7  9  19971023
'LMN'  0,2  735  19970311

I would like to get:

 X1:
 'ABC'  0,5  46  19970224
 'ABC'  0,6  29  19970424
X2:
 'EFD'  0,5  145  19970218
 'EFD'  0,5  36  19970206
X3:
'GHI'  0,7  9  19971023
X4: 
'LMN'  0,2  735  19970311

Can anyone help? Considering my variable type is 'cell', with both strings and numbers.

firm={'ABC'  0,5  46  19970224
'ABC'  0,6  29  19970424
'EFD'  0,5  145  19970218
'EFD'  0,5  36  19970206
'GHI'  0,7  9  19971023
'LMN'  0,2  735  19970311}
[a,b,c]=unique(firm(:,1))
out=accumarray(c,(1:numel(c))',[],@(x) {firm(x,:)})
out{1}
out{2}
out{3}
out{4}

omg it worked perfectly! I don't think I would have ever arrived to such a simple but very very efficient code! thank you a lot!

[Maria]

Do you know how can I know apply the sort/ or sortrows function for each new cell? I have a X cell and then I get X{1,1} cell and I am not being able to do the usual sort! Thanks!

[Azzi Abdelmalek]

out1=cellfun(@(x) sortrows(x),out,'un',0)

[Maria]

It works! And I guess if I want to sort by a specif column I just add like this:

FAF3_97=cellfun(@(x) sortrows(x,[1, 13]),FAF2_97,'un',0);

At least it seems to be working! Thank you :)

This is correct
