How to create a square matrix based on user input,then show it with surf command and also it have to repeat until user write same m and n matrix inputs? I though this would help from the start,but this is not even working for me. m=inpu...
the assiment is a challange -to create this matrix in one row of code by using Matlab methods ( also multiplying metrix and Vectors are permited ). i cant write the matrix directly(also simple operations example: [1;1;1]+[2;2;2] to get [3;3;3].) ...
对于乘法、除法、乘方等三种数组运算，应按点乘（。*）、点除（。/）、点乘方（。^）来进行运算。所以y1，y2，y3的表达式应改写为 y1=max(1,2./((x).^2+1).^0.5);y2=min(1,2./((x).^2+1).^0.5);y3=(4./((x).^2+1)).^0.25;运行结果如下 x...
行数和列数相等的矩阵称为方阵(Square Matrix),逆矩阵和可逆矩阵都是方阵。数字0没有倒数,同理许多矩阵也没有逆矩阵,非方阵的矩阵就是不可逆的。逆矩阵求法:A^(-1)=(1/|A|)×A* ,其中A^(-1)表示矩阵A的逆矩阵,其中|A|为矩阵A的行列式,A*为矩阵A的伴随矩阵。(这个暂时不需要掌握,现在一般都用...
x^3就是矩阵运算，你设的x是一个行向量，自乘无法实现。要实现每一个数的计算。改成：y=x.^3+2.*x+5 多加一个"."就可以实现 要
\begin{pmatrix} E_{N} \\H_{N} \end{pmatrix} =\exp(ikD) \begin{pmatrix} E_{N+2}\\H_{N+2} \end{pmatrix} 由此我们可以得到: \det[M_{a}M_{b}-\exp(ikD)]=0 对于一维包含两种介质的光子晶体,正入射时色散关系有如下解析表达式: ...
