Alternative to interp2
显示 更早的评论
I am trying to interpolate values in a 2d space. But my code is very slow.
I used the tic toc and found that it is because of interp2 being called multiple times. Is there an alternate for it ? that would be faster ?

Hi,
"griddedInterpolant" function will run faster and is recommended by MathWorks as an alternative to calling "interp2" multiple times.
Refer to the following documentation for more information on "griddedInterpolant" function:

Perhaps you are calling interp2 multiple times in a loop, when a single call with multiple points will be far faster. This would be true also with griddedInterpolant. Both tools will be internally optimized to perform much better in a vectorized way.
