在 MATLAB Online 中打开

It is a function in the nnet.internal.cnnhost package directory. Its name is not resizeImage2D but nnet.internal.cnnhost.resizeImage2D. As the "internal" part of the package name indicates, you should not write code depending on the behavior or existence of this function in a future release.

According to the which function, this function is built-in and so you cannot read the code.

>> which -all nnet.internal.cnnhost.resizeImage2D
resizeImage2D is a built-in method  % static method or package function

it is from a example demo of matlab. i find it support uint8 data to be single type after resize.

maybe it is from a c file.

i think it is for reducing ram space for gpu computation.

and imresize (the data type won't be changed) will be ok if there is enough gpu ram.

thank you!

It's built-in and there is no help text for it. Don't write code that depends on it functioning a particular way or even it existing in a future release.
