Z must be a matrix, not scalar or vector - surface plot

Hello,

Attached is a screenshot of my code and a table I recreated in excel. Just pretend it is in MATLAB. Unfortunaltly, because this is for work, I cannot share actual screenshots, so I made a simplified mock up to show you.

'bs' is the variable name I call from.

The table is a 1x4 structure with 4 fields. I converted the data to a table as this fixed my issue last time, but now I get the error 'Z must be a matrix, not scalar or vector' again.

I appreciate any help/advice. Thanks!

You use surf when you have z value for each combination of x and y vectors. Here, you have x, y, and z vectors, so you should draw a 3D scatter plot using scatter3() function.

scatter3 (tbl.temp, tbl.humid, tbl.k);
