Operator '-' is not supported for operands of type 'cell'.

I am having some problem with obtaining a calculation as it is followed by this error:

Operator '-' is not supported for operands of type 'cell'.

Error in Tumbledata_user (line 28)
VSFR=cos(radians)*((ATtable{1,3} - (ATtable{1,5}))/(2*Rs)) %Vertical readings-scale factor

Then try to perform the calculation: VSFR=cos(radians)*((ATtable{1,3} - (ATtable{1,5}))/(2*Rs)). I am subtracting certain values from the table.

I am wondering why I am receiving the error: Operator '-' is not supported for operands of type 'cell'. And how to resolve this issue.

Check the contents of ATtable{1,3} and ATtable{1,5}. I bet they're not numbers.

Well, attach ATtable in a .mat file and we can study it more closely.

There are quotes around the contents of your table entries. A table containing numbers would just have numbers, like this:

If you are using a current release of MATLAB, you can do a detectImportOptions and then set the VariableOptions properties Prefixes and Suffixes to include the apostrophe, I think.

See: Position and extraction of row. We may have serendipitously solved this with str2double.
