Question

Hi

i Have this function

function Vl=varmelackage(tempU)
    tempU=xlsread('temperatur.xlsx','D3290:D3654')
    h=24
    l=2*10^6
    tempIn=22
    Vl=(h*l)/(tempIn-tempU)
end

i would now like to both be able to retun all function values corresponding to each value in the table "temperatur.xlsx", and i would also like to plot the function. How do i do this?

but readtable doesnt really help me i think

i would like to be able to plot Vl, but if i run the function, i get a vector with all zeros, even though my input is a long vector of different numbers, and my function is relatively simple

so then the plot of the function using fplot just becomes a straight line along the x-axis...
