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

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.

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)
but it says Warning: Matrix dimensions must agree, not rendering mesh. round(3.14) ans = 3 round(pi) ans = 3 x=1:5; min(x) ans = 1 x=[1 2 3 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. Check your F.

Try the following: n1=1; n2=2; n3=3; n1
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 ???

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.
