Apply equation to an array of values producing a new data set

Hi there,

I have an equation:

e = 0.61121*exp((18.678-i/234.5).*(i./(257.14+i)))

where i are my values in my data set of temperature, ranging from 1 to 122736 values.

I want to apply this equation to all the values in my temperature data set, and produce a new data set of variables (e).

I'm thinking this would be best done in a loop, but I am just unsure of how to link my data set to the loop.

What I have so far is:

for i=1:122736
    e = 0.61121*exp((18.678-i/234.5).*(i./(257.14+i)))
end

any help would be much appreciated.

Cheers :D

    e = 0.61121*exp((18.678-Temperature/234.5).*(Temperature./(257.14+Temperature)));
    

where Temperature is your 1 x 122736 vector of temperature values.

You do not need a door loop. Matlab is built to handle this kind of operation. Check the following:

T = 1:1:122736;
FcnT = 0.61121*exp((18.678-T/234.5).*(T./(257.14+T)));

Hi Erivelton,

Does this still work if my T values are of the following (attached), with values ranging from 1-122736? Sorry if I was unclear.

[Erivelton Gualter]

It does.
