strange

Arguments

x

real or complex vector or matrix

Description

The range is the distance between the largest and smallest value, [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 ]
