I have 4 arrays. Each one is 39690x1 double. I need to combine them into one array that is 4x39690 double.

inp = cat(2,He,Lu);

inp = inp';

This works when I combine two arrays.

imp = cat(4,S1,S2,S3,S4);

inp = inp';

But when I try it on 4 arrays it gives me errors: Error using '

TRANSPOSE does not support N-D arrays. Use PAGETRANSPOSE/PAGECTRANSPOSE to

transpose pages or PERMUTE to reorder dimensions of N-D arrays.

I tried out permute but can only find examples on how to use it on 3D images or excel files, it doesn't do what I need. And I can't find much at all on how to use PAGETRANSPOSE.

在 MATLAB Online 中打开

s1 = rand(5,1);
s2 = rand(5,1);
s3 = rand(5,1);
s4 = rand(5,1);
imp =[s1 s2 s3 s4]'
imp = 4×5

% or
imp1 = cat(2, s1, s2, s3, s4)'    % 2 along dim 2
imp1 = 4×5
