A = [3    148    117    148   145    178   132    174
2    176    174    110   185    155   118    165
0    100    124    113   193    136   146    108
0    155    170    106   158    130   178    170
9    196    138    113   108    127   144    139
6    188    143    183   137    162   105    169
9    122    156    119   188    179   100    151
8    176    137    114   135    123   134    183] ;
threshold = 100 ; 

idx = A<threshold ;
A(idx) = 0 ;

A(idx) = 0? is there a semicolon or no?

[KSSV]

idx is a logical matrix, no need to use semicolon.
