Hi,
I have a cell array and need to convert to array.
a = {[100, 200, 300, 400, 500], [1000, 2000, 3000, 4000, 5000], [1100,1200, 1300, 1400, 1500]};
for each set b = a(1);
I need array data like,
b = [100, 200, 300, 400, 500];
i tired cell to mat, its not working.

If you want to extract the content of one cell simply do:
b = a{1};
If you want to merge a couple of cells into an array or matrix you can do:
B2 = cell2mat(a([1 3]));
B3 = cell2mat(a([1,3])');

You're welcome.
The reason was that you confused the two different indexings on cell-arrays, and then the data-format in the cell. When runing into these problems look at the data-type of the intermediate variables - that should reveal some of the reasons for the results or errors you get - for this I typically use (in your example):
whos b
That will tell the size and data-type of the variable b.
