i have two tables, 1table is for power and other one is for area, if do have data in table 1

i have two tables, 1table is for power and other one is for area, if I do have data in table 1 how would i know the equivalent value on that number to table 2? table 1 ranges 700-800 and table2 ranges 100-300..

TABLE same as here

POWER(700-800)         AREA(100-300)
800                          300
799                          299
798                          298
...                          ....
...                          ...
down to 1                   down to 1

You could use one of Matlab's interpolation functions. Just ensure that your power and area tables are the same size. See:

doc interp1

Example:

mPower = [700 750 800];
mArea = [100 200 300];
mInputPower = 720;

outputArea = interp1(mPower, mArea, mInputPower);

hmmm I am new at matlab a little bit confusing about the code... okay consider i have matlab calculator which computer power,area,etc... then i am solving for elevation(which ranges is from 700-800).. then capacity(ranges 100-300).. i wanted to know if i got result for elevation i want to know the equivalent value of that result in elevation to the capacity..

for example i got result EL = 760 what is the equivalent value of capactiy which ranges 100-300?

above code can do that? please answer.. thanks I appreciate your reply...

Yes, Chris's code does handle that, if you have appropriate mPower and mArea vectors, provided that capacity depends only on elevation.

i got a new problem now, if ever i get a decimal result like 701.2,703.2 or any decimal value? can interp handle that?

[Walter Roberson]

Yes, no problem.
