A vectorized objective function accepts a matrix as input and generates a vector of function values, where each function value corresponds to one row or column of the input matrix.patternsearchresolves the ambiguity in whether the rows or columns of the matrix represent the points of a pattern ...
MATLAB Online에서 열기 I am currently testing a small matrix D while I am in the early stages but later on, the matrix could be as large as 200 by 500 by 500. I am looking for a method to run my loops faster. What is a smart way to vectorize this code?
Define a MATLAB®function that performs in an addition operation on a matrix within aforloop. Call thecoder.loop.vectorizefunction immediately before the for-loop in your function. functionout = vectorizeForLoops(x,y) out = initRow(100); coder.loop.vectorize("i");fori = 1:100 K = y...
MATLAB Online에서 열기 Hi, Can this code be vectorized. If so, can someone help me to do so. Thanks in advance. C is a 201*201 2D matrix. forl=2:N-1 form= 2:N-1 rd=randi([0 8]); ifrd ==0 C(l,m)=C(l,m) - 1; ...
vectorize a for loopLoops are not always evil, and in this case probably even faster than the alternatives.@Azzi: I prefer to write fast code for all cases. A useful piece of code is used in larger programs also and then the total speed is limited by the most time consuming parts. A ...

Basically what I want to do is for each x,y,z point in 101x21x100 3D-matrix P, I want to calculate loads from each load with coordinates x,y,z and quantity (defined by 201x21 matrices Qx,Qy,Qz and Qq) and then sum all the loads into each x,y,z poin...
Open in MATLAB Online My problem: I'm trying not to use a for loop to increase the value of the elements in a matrix that happens to be the field of an array of structs which is a property of an array of objects. Thia is the overview: ...
As I mentioned to Lennart, it would probably also be of benefit to use nlinfit's Jacobian option with this. The Jacobian should turn out to be a very sparse block diagonal matrix. By computing it yourself, you would communicate that sparsity to nlinfit, as well as the separable structure ...
How to vectorize a for loop that computes the expected value with multidimensional arrays?Thank you very much Matt. Your faster version of the code motivates me to continue learning the Matlab language. Thanks again.
