Overlay two pointclouds to compare them

ptCloudA=readmatrix('Herramienta_1_1.txt');
ptCloudB=readmatrix('Herramienta_1_12.txt');
>> pcshowpair(ptCloudA,ptCloudB)
Error using pcshowpair
Expected ptCloudA to be one of these types:

pointCloud

Instead its type was double.

Error in pcshowpair (line 76)
validateattributes(ptCloudA, {'pointCloud'}, {'scalar'}, 'pcshowpair', 'ptCloudA');

Hello, I have two .txt files with points cloud from a confocal microscope. I want to plot both points cloud and overlay them. I have tried the above but this error appears. I´m really noon in matlab so i dont understand anything.

I have managed to display both by applying this:

>> ptCloudA=readmatrix('Herramienta_1_1.txt');
ptCloudB=readmatrix('Herramienta_1_12.txt');
pcshow(ptCloudA,'b') 
hold on
pcshow(ptCloudB,'r')

but i would like to know how to use the pcshowpair command.

Thanks

The inputs ptCloudA & ptCloudB should be pointCloud objects, refer to the documentation of pcshowpair for more information.

Refer to the documentation of pointCloud for converting the matrices ptCloudA & ptCloudB into pointCloud objects.
