how could it be done for finding first which array of a cell is equal a specified string and in second, what is number of column that contains this string
for example:
CELL={'a','b','c','d','e','f',...}
finding 'a' in CELL?(which row and column)

CELL={'a','b','c';'d','e','f'};
[Row,Col]=ind2sub(size(CELL),find(ismember(CELL,'e')))
or
[Row,Col]=ind2sub(size(CELL),find(strcmp(CELL,'e')))

ind2sub function is unnecessary:
[row col] = find(strcmp(CELL,'a'))

Grzegorz Knor's find(strcmp(C, 'a')) is the fastest solution.

find(char(CELL)=='a')
Does that help?

sorry should be
find(char(CELL)=='a');

See in documentation:
doc strfind
strfind(CELL,'a')

CELL={'a','b','c','d','e','f';'f','e','d','c','b','a'}
idx = strfind(CELL,'a');
[row col] = find(~cellfun(@isempty,idx))

I definitely prefer Grzegorz's solution in the comment above:
find(strcmp(C, 'a'))
