Error using ==> horzcat CAT arguments dimensions are not consistent.

this is the code and i cant undrestand why i get this error.please help me. features is a 8*3 matrix

function predicted_score = bliinds_prediction(features)

% features: needs to be a ROW vector of features

Answer 1

[Matt J]

[features i] isn't a possible concatenation if features is 8x3 and i is a scalar

[Jila]

i use reshape(feature,1,24) because i see [features i]-mu and mu is 1*24.I was not significant to [features i] but problem is solved.how?!!!
