Data Types in Matlab

Must read

Class require different storage amounts logical value or 8-bit integer is the smallest of all and it require 1byte.


  • Use for signed and unsigned whole numbers.
  • Most efficiently use of memory.
  • intmin and intmax useful to show the range of values.
  • Chooses from 4 different sizes (8, 16, 32, and 64 bits).

       Example: int8, uint8, int16, uint16, int32, uint32, int64, uint64

In matlab it as four signed and unsigned integer classes. Signed work for positive and negative values but wide range of numbers cannot represented as unsigned type.


  • Itconsist of two values i.e., true or false.
  • It is used to test state or for relational condition.
  • It useful for array indexing.
  • Inefficiency of two dimensional arrays.


  • Data type into text.
  • Native or Unicode.
  • Which is used to convert to/from numeric.
  • For multiple strings.


  • It is default numerical type in matlab.
  • To show range of values it uses realmin and realmax.
  • Two-dimensional array can sparse.
  • Floating point number is represented in Double and single precision in matlab.

In matlab default is double but using some techniques we convert into single precision with simple conversion.


  • It require more memory for overhead.
  • Method of passing function arguments.
  • It can access one or all fields in single operation.


  • Cells useful for storing varying classes and size of array.
  • It requires more memory for overhead.
  • In order to handle elements similarly as numeric or logical arrays.
  • To package data as you want it allows you the freedom.


  • Rectangular container will manipulate the mixed-type and column-oriented data.
  • Row names and variable names will identify contents.
  • We can use Table Properties in order to store metadata such as variable units.
  • In order to handle elements similarly as numeric or logical arrays.
  • We can access data in numeric or named index form.


  • Pointer to a function.
  • Enables passing a function to another function.
  • It used to call functions outside for usual scope.
