The Householder transformations are used to zero out all but the first element of vector x. Compute a Householder matrix P1 and perform the transformation A1=P1A. The matrix A1 has only zeros below the diagonal in the first column. Get [v1,beta1] = gallery('house',A(:,1)); P1 = ...
if one ofAorBis a scalar, then the scalar is combined with each element of the other array. Also, vectors with different orientations (one row vector and one column vector) implicitly expand to form a matrix.
Starting vector value, specified as a real numeric scalar. If j < k so that the output vector is not empty, then j is the first element in the vector. Example: x = 0:5 Example: x = 0:0.5:5 Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 |...
6.Problem 6. Select every other element of a vector Write a function which returns every other element of the vector passed in. That is, it returns the all odd-numbered elements, starting with the first. Examples: Input x = [1 3 2 4 3 5] Output y is [1 2 3] Input x = [5 9...
This definition also extends naturally to arrays with more than two dimensions. For example, ifXis an N-D array of sizem-by-n-by-p-by-...-by-q, then the Frobenius norm is ‖X‖F=⎹⎷m∑i=1n∑j=1p∑k=1...q∑w=1∣aijk...w∣2. ...
In this example, the third argument of thefind()function is used with the string'last'to set the direction of searching from the last element towards the first. Consequently, the last two zero values are removed from the vectorn. Output: ...

Loglikelihood objective function value, returned as a numeric scalar or a numpaths-element numeric vector. logL(j) corresponds to the response path in Y(:,:,j) or the path (column) j of the selected response variables of Tbl1.
Vector Magnitude Create a vector and calculate the magnitude. v = [1 -2 3]; n = norm(v) n = 3.7417 1-Norm of Vector Calculate the 1-norm of a vector, which is the sum of the element magnitudes. v = [-2 3 -1]; n = norm(v,1) ...
J = besselj(nu,Z)computes theBessel function of the first kindJν(z)for each element in arrayZ. example J = besselj(nu,Z,scale)specifies whether to exponentially scale the Bessel function of the first kind to avoid overflow or loss of accuracy. Ifscaleis1, then the output ofbesseljis ...
