min Into range Array

[turbofib]

look that:

a=[ 3 1 8 2; 5 7 8 3;7 8 9 6;0 2 6 1]

i need to search min between 2 index

example:



min between position 2 and 4 element

RIS=1 3 6 1 (1 is min between 1 8 2, 3 is min between 7 8 3, 6 is min
between 8 9 6....

it's possible to do this avoid loop?

thank very

Hi,

a=[ 3 1 8 2; 5 7 8 3;7 8 9 6;0 2 6 1];
b = min (a(:,2:end), [], 2)

excuse me..

another question :

a=[nan nan nan;nan nan nan;nan nan nan]
v=[2 1 1]

a((end-v):end,:)=0

i want this:

[nan nan 0;nan 0 0;nan 0 0]

i try it but don't run
