dear colleages… i have a problem with a table… here is the problem….

i got a table named depth:

` depth(:,1)=a1; depth(:,2)=g1; i need to create two new tables (submarine and aerea) each one composed by selected values of the table depth and also composed by two columns each one:`

for submarine: i need all negative values of the second column of depth (depth(:,2), with each corresponding value of the first colum of depth (depth(:,1).

for aerea: the same but positve values…

i prepare this but dosent work

` submarine=find((depth(:,2)<0,:)); aerea=find((depth(:,2)>0,:));`

i think, find is not correct to be used in this case…. but what can i use?

thanx
