Matrix function [row:column] help

Latest activity Answered by Fangjun Jiang

When playing with the matrix B1 I am confused about what the result from RowColumn does. When I run the program it results in 1 but I don't understand the reasoning behind it. Can someone please explain this to me?
B1 = [2 4 6 8; 10 12 14 16; 18 20 22 24; 26 28 30 32]
idx_8=find(B1==8)
[row,column]=find(B1~=8)
RowColumn = [row:column]
