  2. zeros - Create array of all zeros - MATLAB - MathWorks

    www.mathworks.com/help/matlab/ref/zeros.html

    To create a GPU array with underlying type , specify the underlying type as an additional argument before . For example, X = zeros (3,datatype,'gpuArray') creates a 3-by-3 GPU array of zeros with underlying type. If you specify as a gpuArray, the underlying type of the returned array is the same as. Distributed Arrays.

  3. In practice, all is a natural extension of the logical AND operator. If A is a vector, then all(A) returns logical 1 (true) if all the elements are nonzero and returns logical 0 (false) if one or more elements are zero. If A is a nonempty matrix, then all(A) treats the columns of A as vectors and returns a row vector of logical 1 s and 0 s.

  4. pzmap - Pole-zero map of dynamic system - MATLAB - MathWorks

    www.mathworks.com/help/control/ref/lti.pzmap.html

    pzmap(sys) plots a pole-zero map for sys. In the plot, x and o represent poles and zeros, respectively. For SISO systems, pzmap plots the system poles and zeros. For MIMO systems, pzmap plots the system poles and transmission zeros.

  5. Finding the zeros of a function - MATLAB Answers - MathWorks

    www.mathworks.com/matlabcentral/answers/89577

    See that there were 85 intervals found where a sign change occurred. I carefully chose code such that the first interval would be found, so fzero will find the zero at 0. ninter = numel (scinter) ninter =. 85. xroots = NaN (1,ninter); for i = 1:ninter. xroots (i) = fzero (fun,xs (scinter (i) + [0 1])); end.

  6. roots - Polynomial roots - MATLAB - MathWorks

    www.mathworks.com/help/matlab/ref/roots.html

    Description. r = roots(p) returns the roots of the polynomial represented by the coefficients in p as a column vector r. Input p is a vector containing n+1 polynomial coefficients, starting with the coefficient of xn. For example, p = [3 2. -2] represents the polynomial 3 x 2 + 2 x − 2. A coefficient of 0 indicates an intermediate power that ...

  7. eye - Identity matrix - MATLAB - MathWorks

    www.mathworks.com/help/matlab/ref/eye.html

    I = eye(n) returns an n -by- n identity matrix with ones on the main diagonal and zeros elsewhere. example. I = eye(n,m) returns an n -by- m matrix with ones on the main diagonal and zeros elsewhere. example. I = eye(sz) returns an array with ones on the main diagonal and zeros elsewhere. The size vector, sz, defines size(I).

  8. Transfer Functions - MATLAB & Simulink - MathWorks

    www.mathworks.com/help/control/ug/transfer-functions.html

    Create the transfer function G (s) = s s 2 + 3 s + 2: num = [1 0]; den = [1 3 2]; G = tf(num,den); num and den are the numerator and denominator polynomial coefficients in descending powers of s. For example, den = [1 3 2] represents the denominator polynomial s2 + 3s + 2. G is a tf model object, which is a data container for representing ...

  9. any - Determine if any array elements are nonzero - MATLAB -...

    www.mathworks.com/help/matlab/ref/any.html

    any(A) returns logical 1 (true) if any of the elements of A is a nonzero number or is logical 1, and returns logical 0 (false) if all the elements are zero. If A is a nonempty, nonvector matrix, then B = any(A) treats the columns of A as vectors, returning a row vector of logical 1 s and 0 s. If A is an empty 0-by-0 matrix, any(A) returns ...

  10. function - Declare function name, inputs, and outputs - MATLAB -...

    www.mathworks.com/help/matlab/ref/function.html

    Description. function [y1,...,yN] = myfun(x1,...,xM) declares a function named myfun that accepts inputs x1,...,xM and returns outputs y1,...,yN. This declaration statement must be the first executable line of the function. Valid function names begin with an alphabetic character, and can contain letters, numbers, or underscores.
