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...
If they are the same, merge the two matrices, such as [3;2]∪[3;5]=[2;3;5],[4; 2]∪[4;5]=[2;4;5], [5;2] does not have the same number 5 in the first row and first column, so keep it directly.In the end, Rule3 becomes {[2;3;5][2;4;5][5;2]}. I hope ...

Rather than doing the above I am wondering if there is any other way to ignoring the NaNs -- I know of sum(...,'omitnan') and nansum() but they work on one matrix or if I concatenate the two matrices together then they aggregate either all ro...

All variables of all data types in MATLAB are multidimensional arrays. A vector is a one-dimensional array and a matrix is a two-dimensional array.We have already discussed vectors and matrices. In this chapter, we will discuss multidimensional arrays. However, before that, let us discuss some...
A 3D matrix or array is different from a 2D matrix or array. In a 2D matrix, we encounter two dimensions – rows and columns. The first dimension signifies the row, while the second denotes the column. However, when delving into the realm of 3D matrices, an additional dimension emerges,...

Working with arrays or matrices, optimization, or plotting requires additional libraries to be installed. Fortunately, if you install Python with the Anaconda installer these libraries come preinstalled and you don’t need to worry. Even if you’re not using Anaconda, they are usually pretty easy...
