  • 1. Matlab:Organizing Data
  • 2. Contents:
    Cell Arrays
    Function Handles
    Structures
  • 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.
