Hi,
why comes this error? I use MATLAB2020
Undefined function 'estimateGeomerticTransform' for input arguments of type 'SURFPoints'
%%
clear all;
refIm = imread('bohemian.jpg');
croppedIm = imcrop(refIm);
%%
refIm = rgb2gray(refIm);
descentIm = rgb2gray(croppedIm);
descentIm = imrotate(descentIm,90);
imshowpair(descentIm,refIm,'montage');
%%
refImPoints = detectSURFFeatures(refIm);
descentImPoints = detectSURFFeatures(descentIm);
%%

imshow(descentIm);
hold on;

There is a typo in your code, estimateGeomerticTransform should be estimateGeometricTransform.
