MATLAB: une référence sur les messages d'erreur

Voici certaines des erreurs les plus courantes:

%# create two arrays, one 3-by-3, one 4-by-4 (see 'help magic' for details about them)
>> m3 = magic(3);
>> m4 = magic(4);

%# matrix multiplication error. Arrays must be X-by-Y and Y-by-Z
>> m3*m4
??? Error using ==> mtimes
Inner matrix dimensions must agree.

%# cannot multiply (add, subtract...) element-wise if not the same number of elements 
>> m3.*m4
??? Error using ==> times
Matrix dimensions must agree.

%# m3 is 3-by-3, and thus has only 9 elements. There is no element #10
>> m3(10)
??? Index exceeds matrix dimensions.

%# there is also no element #-1 
>> m3(-1)
??? Index exceeds matrix dimensions.

%# can only index with integers or logicals
>> m3(2.2)
??? Subscript indices must either be real positive integers or logicals.

%# m5 has not been defined yet. This is the "probably a typo"-error
>> m5(3)
??? Undefined function or method 'm5' for input arguments of type 'double'.

%# Cannot assign the elements of m4 to m3, because they don't have the same number of elements.
%# m3(:) = m4(1:9) would work.
>> m3(:) = m4(:)
???  In an assignment  A(:) = B, the number of elements in A and B
must be the same
