In this code, the contourslice line is not running. It's showing index in position 1 is invalid. Array indices must be positive integers or logical avalues.
I am not able to get the contour in the figure.

Click the "Edit" button, change whatever you like in the code and click "Run" to execute.

Since I notice you already have the above code running fine on MATLAB, can you pinpoint where exactly are you facing the error ? Also the commented lines are adding to the confusion.
Thanks
