vArr = [ 5 5 5 5; 5 5 5 5 ; 5 5 5 5; 5 5 5 5; 5 5 5 5 ]

so i have this and i knw how to change one element but how to change whole colum??

i tired this vArr( :, 3 ) - 2 but then only shows one column

[James Tursa]

vArr(:,3) is the 3rd column. vArr(:,2) is the 2nd column. Etc.

Answer 1

[James Tursa]

vArr(:,2) = _____;  % <-- you fill in the blank

not working

[James Tursa]

What did you fill in the blank with? What does your current code look like?

[nty huy]

need to change 2nd column to 3s

vArr( 1:end,3)-2

but it wont show to all just

one column

[James Tursa]

Why are you using the minus operator - instead of the assignment operator = as I show? Why are you indexing into the 3rd column instead of the 2nd column?
