The third dimension represents all the slices needed to represent the entire brain. http://projectdataline.com/error-using/error-using-sym-mpower-matrix-must-be-square.html How to plot f(x,y)=1-(1-1/y)^x using matlab I got "Error using ==> mrdivide Matrix dimensions"? mat2=mat1; mat2(1:10, 3)=1   Another way of writing this command would be as follows, here instead of having to know that mat2 has ten rows, we use the Error using ==> rdivide Matrix dimensions must agree.   Here's another example.

Define a 2 by 3 matrix A. It's not an array with values of 4,5,6,7,8,9,10,11,12. You need to transpose one of them. 0 Comments Show all comments Chandra Shekhar (view profile) 25 questions 11 answers 5 accepted answers Reputation: 22 Vote0 Link Direct link to this navigate here The newsgroups are a worldwide forum that is open to everyone.

Like with addition and subtraction the vectors must be the same shape.

You can a multiply a scalar with another scalar, with a vector, or with a matrix. 2*3   ans =      6   2/3   ans = mat2=mat1;   mat2(:, 3)=1   mat2 =      0     0     1     0     0     0     0     0      0     0     1     0     0     0     0     0      0     0     1     0     The second value of size is the number of columns.   Now try: vect1=[1 2 4 6 3] vect2=vect1'   vect1 =      1     2     4     6     3 vect2 The expression above gives you a 0 because the statement is false.

Subscripted assignment dimension mismatch.   Weirdly, the following command, which seems identical, will work.

They must be the same size to use ".*". c = k.*(m.*s./f.*g) And for the error itself: unless a==b==n1==n2==lambda, the dimensions of the vectors you create are not the same and you will not be able to (element-wisely) multiply them,

Many variables were defined before the code he gave us and we don't know what they are, or even if they're arrays or scalars.

However, the documentation indicates that it will output a column vector.

You will have to transpose one of the two.
