In the first two dimensions, the rules of matrix multiplication apply. If either operand is a scalar, then the result has the size of the nonscalar operand. When both operands are matrices, multiplying anm-by-n
Mesh the conformal array. You can control the mesh of individual elements by specifying a vector of edge lengths. mesh(c,MaxEdgeLength=[0.05 0.2 0.05]); More About expand all References [1] Balanis, Constantine A.Antenna Theory: Analysis and Design. 3rd Ed. New York: John Wiley and Sons...
Multiply the factors to recreateA. With the two-input syntax,luincorporates the permutation matrixPdirectly into theLfactor, such that theLbeing returned is reallyP'*Land thusA = L*U. Get L*U ans =3×310 -7 0 -3 2 6 5 -1 5 You can specify three outputs to separate the permutation...

Create a row vectoraand a column vectorb, then multiply them. The 1-by-3 row vector and 4-by-1 column vector combine to produce a 4-by-3 matrix. a = 1:3; b = (1:4)'; a.*b ans =4×31 2 3 2 4 6 3 6 9 4 8 12 ...
Again, a variable ne is used to hold the number in row 1 and column 1 of mat2, which is the number of triangular finite elements. Five 16×1 matrices ie,a,b,c and e hold the information stored in row 2 to 17, column 1,2,3,4 and 5 of mat2 respectively. Matrix ie contains ...
In each packet generation, for the kth user, the kth element of the PSDULength property of the cfg input indicates the number of data bytes in its stream. To compute the number of bits, multiply PSDULength by 8. Internally, the function loops this input to generate the specified number ...
将下列语句保存在一个文件名为matrix.m的Matlab脚本文件里:clc;clear;disp('This program multiplies two m x m matrices A and B.');m=input('Enter a value for m: ');A=zeros(m,m);B=A;C=A;for i=1:m str=sprintf('Enter row %d of A as an array: ',i);A(i,:)=input...
% The size of A can be retrieved using A([],'size'). The matrix % is never formed explicitly, thus saving memory. % elements in A. % b Vector containing the rhs of the test problem. % x Vector containing the exact solution, with elements ...
8 setdiff(A,B,'rows') Treats each row of A and each row of B as single entities and returns the rows from A that are not in B. The rows of the returned matrix are in sorted order. The 'rows' option does not support cell arrays. ...
