Error Using Times Matrix Dimensions Must Agree

Contents

The code uses fix(Ts*Fs) to ensure that the result is integral, but depending on the exact bit patterns involved in the round-off, fix() could end up with the integer one lower You can’t add vect1 and vect2 together since they are different sizes. What do you mean with 'my graph'? Basically it is one for loop inside another. http://projectdataline.com/error-using/error-using-times-matrix-dimensions.html

Roger Stafford Subject: Error using times, Matrix dimensions must agree From: salman salman (view profile) 84 posts Date: 17 May, 2011 05:39:02 Message: 3 of 4 Reply to this message Add It would be better style to make the two vectors match in shape by transposing the right hand side as follows:     mat7(:, i)=[0 0 1 1 0]'+i   MATLAB Central is hosted by MathWorks. n1?

We can't really help more because you did not put in any comments to help us figure out what you want to do. When i is two, then the vector [2 2 3 3 2] is put into the second row of mat7 and so on. Search To add search criteria to your watch list, search for the desired term in the search box.

There are thousands of newsgroups, each addressing a single topic or area of interest. In programming a scalar is defined as a quantity that can only hold a single value at a time, i.e. What about the complex number, sigma_f_Jpsi? It may help you to help me.

We are doing this using a for loop. Error Using * Matlab Inner Matrix Dimensions Must Agree BUG BOX – Subscripted assignment dimension mismatch x=zeros(4); x(2, :)=1:5;   ??? Please help me in figuring out the soln of the error??? You will be notified whenever the author makes a post.

This expansion means there's now enough space for y.  This is very weird and at this point you shouldn't worry about it much. Point-wise (or element by element) multiplication and division is the first, and simplest.

Your vector hd is a row vector, so it does not actually have the same dimension. mat6=zeros(6); mat6(2:5, 1:3)=1   mat6 =      0     0     0     0     0     0      1     1     1     0     0     0      1     1     1     0     0     0      1     1     Error Using Times Matrix Dimensions Must Agree vect1+3   ans =      4     5     7     9     6   You can subtract a scalar.

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)  

Since p2 is a scalar, the value it has after the p2 loop has ended is simply 12.

Check your F.

Note that the number of columns in A needs to match the number of rows in B. z1=x*y'   z1 =    18.7000   z2=y*x'   z2 =    18.7000   Note that you get the same answer both times. Is there an elegant way to prove a function is linear? Here are a few examples of operations that aren't allowed because the number of columns in A doesn't match the number of rows in B B*A   ???

Reload the page to see its updated state. You need to use the period regardless of whether you are taking a vector and raising it to to a single number, taking a single number and raising it to a C=B*A'   C =     50   122     68   167   Then look what happens if we orient the matrices in such a way that A has three rows It's not an array with values of 4,5,6,7,8,9,10,11,12.

mat1 and mat2 were entered differently, but both have 4 rows and 3 columns. When we are on the second row the columns are labeled as 5,6,7,8 and so on … How did we do this? That certainly explains the anomalous size.I certainly agree with you about the inadvisability of debugging as an online iterative process![EDIT] — ‘dp12’ is definitely the problem!
