To get all the elements of the nth column in a matrix , you can make use of A (:,n) where n represents the column no in the matrix.A(:,n). ExampleNow, let us create a column vector v, from all the elements of the 4th column of the matrix a. This will be as follows...
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-nmatrix with ann-by-qmatrix results in anm-by-qmatrix. ...

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. L*U ans =3×310 -7 0 -3 2 6 5 -1 5 You can specify three outputs to separate the permutation matr...
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...

function matrix()本函数注意以下几个方面 1.所有fprintf中\r\n也可以用\n表示 这个主要看你的文本查看器支持 如果是WINDOWS的记事本看matrix.txt的话,最好用\r\n 2.输出语句fprintf(fid,'%.1f ',C(i,j));我觉得用fprintf(fid,'%4.1f ',C(i,j));产生的数据会更整齐一些 不过你给的...
