strange
range
Syntax
r = strange(x) r = strange(x, orientation)
Arguments
- x
real or complex vector or matrix
- orientation
index of the dimension along which the strange is computed. It can be either
- a character
"*"
(default),"r"
or"c"
- a positive integer: 1 or 2. 1 is equivalent to "r" and 2 is equivalent to "c".
- a character
- r
real or complex scalar or vector
Description
The range is the distance between the largest and smallest value, r = strange(x) or r = strange(x, "*") computes the range of vector or matrix x.
r = strange(x,'r') (or equivalently r = strange(x,1)) give a row vector with the range of each column.
r = strange(x,'c') (or equivalently r = strange(x,2)) give a column vector with the range of each row.
Examples
x = [22 63 57 24 31 76 85 67 24 94 1 69 73 22 22 34 88 20 89 32 67 7 55 66 37 ]; strange(x) // 94-1 = 93 strange(x, 'r') // [ 76-1=75 88-7=81 73-20=53 89-22=67 94-22=72 ] strange(x, 'c') // [ 63-22=41 ; 94-24=70 ; 73-1=72 ; 89-20=69 ; 67-7=60 ]
