subtract two data points in a cell array
显示 更早的评论
Hi. I have a cell array Sa (338 X 1929). I want to subtract two points (which are numbers). For example: Sa(i,2)-Sa(i-1,2). Matlab doesn't do that as they are cell array type. Is there any way to do this?

After you read the FAQ you will know all about cells and won't need to ask a question like this. See http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F I think it gives a good intuitive description for what cells are an how to use them. Then you will understand why the cyclists answer works.

You are trying to subtract the cells, rather than the contents of the cells. Try
Sa{i,2}-Sa{i-1,2}
