That is not what I want exactly. Because in reality I do not know the matching rows and columns in A. I have B. I need to write a code to search through the array A to find the indices that matches with B. But it should follow that row and column rule that I descibed before....
If this is not the case, then there is no way to distinguish how many matches each row has (unless you also store the row indices, or use linear indices, or find the closest values (e.g. min) rather than trying to find matching values, etc.). Method One: difference and ...
In your case you can use the below code to get the indices of values matching with "value" in column 1 of a matrix 'A'. Indices = find(A(:,1) == value); To get the corresponding values in column 3 in the matrix you can use: ...

In NumPy, slices of arrays are views to the original array. This behavior saves memory and time, since the values in the array don’t have to be copied to a new location. However, it means that changes that you make to a slice from an array will change the original array. You should...
Aggregating Sample Values With Different Sampling Times 下面的方法将数据组合成单个向量,Time_Vector和Data_Vector。然后使用unique()函数来查找Time_Vector中存在的唯一样本时间。通过使用find()函数,for-loop用于评估存在相同采样时间的索引。在找到这些索引之后,通过使用矩阵索引(查找在给定采样时间出现的所有值)获得相...
