Why I got the error "Operator '-' is not supported for operands of type 'struct'."?

My code

%Convert from Fahrenheit to Kelvin

TempK = ((X(:,1)-32)*5/9)+273.15;

How did you create X?

[Ryan Scott]

The X is from a excel file I brought into the code

What code did you use to create X?

[Ryan Scott]

X = importdata('C:\Users\rassc\Downloads\FinalProj_TVdata.csv');
Y = importdata('C:\Users\rassc\Downloads\FinalProj_Pdata.csv');
%Convert from Fahrenheit to Kelvin
TempK = ((X(:,1)-32)*5/9)+273.15;

Can you show the content of your imported data (variable) X?

Answer 1

[Cris LaPierre]

When importing a spreadsheet, importdata returns a scalar structure array (see here). Your error, then, is because you are not accessing the data properly (see examples on the page I linked to).

Is there a reason you are using this import function? I'd suggest using readtable instead. You will have to learn how to access data in a table as well. I'd suggest this short video.

Answer:

X= X.data(:,1);

TempK = ((X1-32)*5/9)+273.15;
