Hello, I'm tryig to normalize separately each column of data in a matrix like T (e.g)

T=5×2 table

LastName Height Age

'Sanchez' 71 29

'Johnson' 69 78

'Lee' 64 14

'Diaz' 67 66

'Brown' 64 88

I used this function: N = normalize(T,'norm',Inf,'DataVariables','Height')

but as this way it uses the max 'Height' value also for the 'Age' column,

i tryed to do N = normalize(T,'norm',Inf,'DataVariables','Height', 'Age')

but it gives me error of inputs...

So, how should I use the function so that each column is normalized by its own max. value?

Thanks!

Try this:

N = normalize(T,'norm',Inf,'DataVariables',{'Height', 'Age'})

Put multiple variables in a cell array (note the curly brackets {}).
