Convert char to multiple cells, each cell takes one string

I have a 1*121 char 'Runtime_Cur','Runtime_Prev','Id_Cur','Id_Prev','Description','PNL','PNL_Cur','valuedate_Cur','PNL_Prev','valuedate_Prev'

cellstr gives me a 1*1 cell, but I would like to get a 1*10 cell, each cell contains one string, so it will be: {'Runtime_Cur','Runtime_Prev','Id_Cur','Id_Prev','Description','PNL','PNL_Cur','valuedate_Cur','PNL_Prev','valuedate_Prev'}

ans =

Columns 1 through 6

    'Runtime_Cur'    'Runtime_Prev'    'Id_Cur'    'Id_Prev'    'Description'    'PNL'

Columns 7 through 10

    'PNL_Cur'    'valuedate_Cur'    'PNL_Prev'    'valuedate_Prev'

Could any one help? Thanks in advance :-)

What is the original variable, the 1*121 char? Can you put it in your question?

Answer 1

[Walter Roberson]

Provided that the literal quote marks do not appear in the middle of a string:

STRING(STRING=='''') = [];
STRcells = regexp(STRING, ',', 'split');

Thanks so much, magic raccoon!

Answer 2

[Fangjun Jiang]

a='Runtime_CurRuntime_PrevId_CurId_PrevDescriptionPNLPNL_Curvaluedate_CurPNL_Prev';
size(a)
b=mat2cell(a,1,[10 10 20 20 18])

Those numbers determines how to split the long string into cells.

Thanks so much, that's what I want. But do u think there is a way of avoiding these numbers?
