help norm norm Matrix or vector norm. norm(X,2) returns the 2-norm of X. norm(X) is the same as norm(X,2). norm(X,1) returns the 1-norm of X. norm(X,Inf) returns the infinity norm of X. norm(X,'fro') returns the Frobenius norm of X. 1. 2. 3. 4. 5. 6. 7. 8...
Explanation:First, Declare the first input matrix. Declaring the second input matrix. Passing the input matrices to the dot function. * Mathematically, the dot product of matrix [3 5 3 6;4 1 6 0;7 3 9 2] and [1 0 3 5;4 3 6 1;7 1 3 0] is (68 6 72 30), As we can se...

Element-wise multiplication operation is one of the useful operations that can be used for a variety of data analysis tasks, such as calculating the dot product of two vectors and multiplying a vector by scalar or matrix by vector. MATLAB makes it easy for the users by introducing the dot ...
matrix P and ‘Q = [3 8 5;1 1 1;3 2 1] ;’ this line load the number in to matrix Q. After that, we used the dot function to calculate the dot product of the matrix. ‘R = dot(P,Q)’ this syntax of the Matlab dot function is used to calculate the dot product of the...

MATLAB (matrix laboratory) is a fourth-generation high-level programming language and interactive environment for numerical computation, visualization and programming.MATLAB is developed by MathWorks.It allows matrix manipulations; plotting of functions and data; implementation of algorithms; creation of user...
但是最终结果却的确能让算法成功运行。很多网上的解释经常会用vector dot product的角度来解释,比如下面这个,但它们对我来说隔靴搔痒,不解决真正为什么这个算法能运行的问题。还望有大神能在算法逻辑上给予指导。 b) Implementation 一整段的代码如下: %% Learningw=zeros(3,1);predictline=plot(xlin,zeros(size(...
