Cell array
in [Matlab]
|
From: Judas Magnus on 2 Apr 2010 16:39 say that I have a string like this: Foods= char('Meat','Chicken','Pork','Duck','Roast') frCell = cellstr(Foods) I want to create a 5 x 5 cell array called cArray containing at 5 random positions the cells of Foods. I know I can create a 5x5 array by cell(5,5) but how can i randomize positions of the frCell into the cArray
From: Matt Fig on 2 Apr 2010 17:00 Look at using the output from randperm as an index into the array.
