3. Cell Arrays A cell array is a collection of containers called cells in which different types of data can be stored.

4. Cell Arrays Use ‘{’ and ‘}’ to define the starting and beginning of a Cell Array.

5. Cell Arrays

6. Cell Arrays Use ‘(’ and ‘)’ to access individual elements of a Cell Array:

7. Cell Arrays Get a row of elements:

8. Cell Arrays Get a column of elements:

9. Cell Arrays Get corner elements

10. Cell Arrays Cell Array Indexing Summary Use curly braces {} for setting or getting the contents of cell arrays. Use parentheses () for indexing into a cell array to collect a subset of cells together in another cell array.

11. Function Handles MATLAB functions are written to named M-files or are produced at the command line as anonymous functions. In either case, a function handle is used to pass the function as an input argument to a function.

12. Function Handles Consider the following function: Save it as the file func1.m

13. Function Handles Using function handles:

14. Structures A structure is a MATLAB data type that provides the means to store selected data together in a single entity. A structure consists mainly of data containers, called fields, and each of these fields stores an array of some MATLAB data type. The figure below shows a structure s that has three fields: a, b, and c.
