MATLAB Onramp 14.1 Project- Stellar Motion Task 7

Modify the Task 2 & 7 section of the script so that it performs the red shift calculation on the second star in spectra, not the sixth.
I have changed s to the second column (s= spectra(:,2)), and that is right.
How do I get the correct values of lambdaHa and speed?

Add an else statement if speed (v) is greater than 0 create a plot of s against lambda using a line width of 3

s = spectra(:,2)
[sHa,idx] = min(s)
lambdaHa = lambda(idx)
z = lambdaHa/656.28 - 1
speed = z*299792.458

tast 2 & 7
s=spectra(:,2)
Did you store the second column of spectra in s?------> this error is not remove..why?

Could some kindly help me with Tasks 2&7 on the MATLAB Onramp on the topic "Project > Stella Motion"?
Here is my answer:
s = spectra(:,2)
[sHa, idx] = min(s)
lambdaHa = lambda(idx)
z = (lambdaHa/656.28) - 1
speed = z*299792.458
I cannot go further beyond this point. Many thanks.

Hi,
The correct values for lambdaHa and speed are calculated using Task 4. At every Task whole of the script runs not the portion of the same.
Thanks

[sHa,idx] = min(spectra(:,2))
to
[sHa,idx] = min(spectra)
