It's not fancy, but did you try taking the histogram (to find integers with counts of 2 or greater) and then just the normal, brute force for loop to replace them with the numbers you want?

I have a code where I'm reading 1024x1024 float matrix from disk then I'm getting some elements of it and doing some process on the new matrix as follows. // mask is the 1Kx1K matrix that 1/64 element of it are 1 other elements are 0; // it is a mask for **Mat data**...
Sum the Elements of a Matrix Using thesum()Function in MATLAB To find the sum of all the elements of a matrix, we can use thesum()function. In the case of a matrix, we have to use thesum()function two times, one for rows and one for columns, but in the case of a vector, we...
Note that this question does not want to be specifically about how to apply an operation elementwise to a matrix, but more generally on how to implement with theano.scan a nested looping construct like the above. Long version: theano.scan (or equivalently in this case, theano.map) a...
Hi I have a case to multiply 2 by 2 matrix with a variable of 50000 elements. how can i do this? w.*[Cm] it doesn't work. 1 Comment Image Analyst on 3 Jul 2022 Open in MATLAB Online If you want a matrix multiplication do ThemeCopy theProduct = w * Cm % or thePro...
Suppose I have the above A matrix. Now I will compare the elements of row one with all other rows of the matrix and if any two elements of other rows become same with the first row then i want to separate them. Similarly, I need to check...

I'm trying to implement some sort of interpolation algorithm. I is an N*4 matrix, holding indices of surrounding points of N other points. But elements in each row of I may not be unique, meaning two or more of them may refer to an individual point. I want to know how ma...
