M1 = rand(2,5,2) ;
M2 = rand(2,5) ;
reshape(cat(3,M1,M2),size(M1,1),[])
ans = 2×15

Hi !
Try this:
M1 = rand(2,5,2) ;
M2 = rand(2,5) ;
M = [M1(:,:,1) M1(:,:,2) M2] ;
size(M)
ans = 1×2
2 15
Maybe there is a better way to do this.

this will work if i put the value of M1 manually ,but i want if the size of M1 also changed that time i should get my result autmatically ,not putting the value manually two times

You can use the reshape(used in reshaping arrays) and cat(used to concatenate arrays) functions in this case:
mat1 = rand(2, 5, 2) ;
mat2 = rand(2, 5) ;
reshape(cat(3, mat1, mat2), size(mat1, 1), [])
ans = 2×15
