after this however, the previous error is gone, but now i want to create the mesh from t and z and then get surface plot for E(z,t).

You can find the size of matrices using the command size.

in the gui I have multiple edit text zones where the user inputs differents values which are lambda,a,b,n1,n2 ! a set of datavalues stored in a matrix/vector/... We are doing this using a for loop.

Opportunities for recent engineering grads. A is a 3 by 2 matrix, B is a 2 by 2 matrix, so the number of columns in A = 2 = number of rows in B.

In that case, if you wanted to look at the first image presented in time you would reference it as follows: mat(:, :, 1) ans = 0 When i is two, then the vector [2 2 3 3 2] is put into the second row of mat7 and so on. That is why. 0 Comments Show all comments Bhagirathi (view profile) 1 question 1 answer 0 accepted answers Reputation: 0 Vote0 Link Direct link to this answer: https://www.mathworks.com/matlabcentral/answers/13175-error-using-times-matrix-dimensions-must-agree#answer_18015 Cancel Copy to Once again you need to provide the size of the matrix and the position in the vector that you want to find the matrix subscripts for. [sub_row, sub_col]=ind2sub(size(mat), 6)

please help me....function trimmedX = myVAD(x); %Author : Olutope Foluso Omogbenigun %Email : olutopeomogbenigun at hotmail.com %University : London Metropolitan University %Date : 02/08/07 %Syntax : trimmedSample = myVAD2(samplex); %This function So if Matlab wanted to be pedantic it would give the Subscripted assignment dimension mismatch error. Then we go through each row of the matrix, and replace the place in the matrix that is the i-th row and i-th column with the number i. Play games and win prizes!

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 United States Patents Trademarks Privacy Policy Preventing Piracy Terms of Use © 1994-2016 The MathWorks, Inc. Basically it is one for loop inside another. You can only upload videos smaller than 600 MB.

mat1 and mat2 were entered differently, but both have 4 rows and 3 columns. vect1+3 ans = 4 5 7 9 6 You can subtract a scalar. I.e.
