I want to set NAN to these cells. Basically i wanted to do a basic threshold operation on a cell array of cell array of matrix . Some of the cells are empty cells, while others have values. If the absolute values in the cells are less than a threshold value say 5, i want to assign a zero to it. The...Empty arrays have no elements, but are of a certain class. All nonabstract classes have a static method named empty that creates an empty array of the same class. The empty method enables you to specify the dimensions of the output array.

- Return subsets of vectors, matrices or data frames which meet conditions. This is a generic function, with methods supplied for matrices, data frames and vectors (including lists). Packages and users can add further methods. For ordinary vectors, the result is simply x[subset & !is.na(subset)]. For
- In that last example, NULL is a special “empty” value (not to be confused with NA, which indicates a missing data point). We’ll look at NULL in detail in Chapter 5 . For convenience, wrapper functions exist for each type to save you typing when creating vectors in this way.
