Arrays in Matlab

• All data in Matlab is actually an array � a 1- or 2-dimensional table of numbers. (We only consider 1-D arrays in this lecture.)

• A single value, called a scalar, is simply an array of size 1.

• To construct a 1-D array, list its elements surrounded by square brackets.

  y = [4 -5 10 0 5.2]
  
  x = [�5 sqrt(2) 17 2^3]

>> a = [4, z, x, y]

a =

4.0000 1.0000 2.7183 1.0000
