I have a 312x3 cell called 'data'. In the first column there are 312 rows of different x-values, the second column there are 312 rows of different y-values, and in the third column there are 312 rows of t-values. I want to collapse all the rows of each column into a single cell, such that all the x-values are in a single cell (first column), all the y-values are in a single cell (second column), and all the t-values are in a single cell (third column). For instance, if I started with the following 6x4 cell array called Data:
Data =
0.935 4 24 0.07
0.759 5 74 0.01
0.681 2 21 0.09
0.823 1 16 0.06
0.894 3 7 0.01
0.953 5 67 0.03
I can't figure out how to transform this into the following 1x4 cell array (Data2)
Data2 =
([0.935 0.759 0.681 0.823 0.894 0.953] [4 5 2 1 3 5] [24 74 21 16 7 67] [0.07 0.01 0.09 0.06 0.01 0.03], :)
Is there a piece of code that can do this?
I hope this makes sense! Thanks for the help.
Best wishes,
Billy

Data2=num2cell(Data,1);
However, I wonder why you would want to do this. Matrices are usually faster to manipulate than cells, and you can do matrix math with them.
