A snapshot of the summary - Matlab

  • Chapter 1

  • Of what does a matrix consist and how can it be coded into matlab?
    Size of a matrix is defined by the number of rows and columns it contains. Matrix with m rows and n columns is called a mxn matrix: A=[1 2 3; -2 -3 -4]
  • What can be used to display the identity code in matlab?
    Function eye
  • What commands can be used to return a nxm matric containing unity or zeros in all entries?
    Ones(n,m) and zeros(n,m)
  • How can you turn a row vector into a column vector? And vice versa
    By the transposition operator (')
  • What does this command tell you: a=[1:2:10]?
    This command tells you that a vector starts on 1, increases with 2 till a final value of 10 is reached.
  • In matlab, what defines the concept length?
    Returns the number of components of a(the dimension of the vector)
  • In matlab, what defines the norm?
    Norm(a) returns the norm of a and is by definition |a|= sqrt(a*a)
  • How can element be extracted from an array?
    A=array 
    Use the command: index=[rows you want to extract];
    B=A(index,:)
    B=
  • For what are the commands sum and sort used?
    Sum returns a row, which contains the sum of the columns in the matrix. If the sum is applied --> returns a single vector. Command sort returns a copy of the input vector with the elements arranged in increasing order/
  • What defines the command whos?
    It will show variables that you have defined and their sizes
