Hello, I have a matrix of dimension 1x185x3. How can I convert it to a single value vector as my other features are single values 50.9 and 92.5. I want to store these three into a same vector, assume Class(i,:)=[Mean Dev1 Matrix]; Please share If you have any command to do this.

Thanks

Properties mean? Sorry I didn't get that. And this matrix is for Mode of Image.

If you want mode of the image, then call mode() . However, it would not be uncommon for entries to not be duplicated in a floating point matrix, so mode() can be pretty meaningless in that case.

If mode() is not what you are looking for, then you need to give us some hints about how the value is to be calculated.

If we call your matrix M and call this calculation function F, then does it have to be the case that F([M(:,1),M(:,2),M(:,3)]) = F(M) ? Is F(M) = F(sort(M)) ? If you have two matrices A and B, then is F(A+B) = F(A) + F(B) ?
