As a simple example, you can add two vectors with the same size. If one operand is a scalar and the other is not, then MATLAB implicitly expands the scalar to be the same size as the other operand. For example, you can compute the element-wise product of a scalar and a matrix. @Dev-iL I don't think the question linked counts as a duplicate. Yes, it does have max(x,y) in the question body but it is in a completely different context. That question states that this command will return the array containing the maximum value (which is actually incorrect) whereas this question is about finding the element-wise maxima. Multiply Row and Column Vectors. Create a row vector a and a column vector b, then multiply them. The 1-by-3 row vector and 6-by-1 column vector combine to produce a 6-by-3 matrix with all combinations of elements multiplied.

Element wise maximum matlab

If I have two N-by-N matrices A and B, how can I find the N-by-by matrix C such that its (m,n)th element is the max of the (m,n)th element in A. Is this possible in matlab? So far the max documentation doesn't seem super helpful. Ideally, it would be important that this element-wise way of. M = max(A) returns the maximum elements of an array. If A is a matrix, then max(A) is a row vector containing the maximum value of each column. For example, if A is a matrix, then max(A,[],2) is a column vector containing the maximum value of each row. This is exactly what the max function does by default: C = max(A,B). max. Maximum elements of an array. Syntax. C = max(A) C = max(A,B) C = max( A,[],dim) [C,I] = max() Description. C = max(A) returns the largest elements. MATLAB® and NumPy/SciPy have a lot in common. For matrix, ``*`` means matrix multiplication, and for element-wise multiplication one has to use the .. max(a), nmdhumanrace.com(0), maximum element of each column of matrix a. Element-wise logical AND . MATLAB/Octave. Python. Description max(a,b) maximum(a,b) pairwise max max of all values in two vectors.
Multiply Row and Column Vectors. Create a row vector a and a column vector b, then multiply them. The 1-by-3 row vector and 6-by-1 column vector combine to produce a 6-by-3 matrix with all combinations of elements multiplied. As a simple example, you can add two vectors with the same size. If one operand is a scalar and the other is not, then MATLAB implicitly expands the scalar to be the same size as the other operand. For example, you can compute the element-wise product of a scalar and a matrix. If A is a vector, then vecnorm returns the norm of the vector. If A is a matrix, then vecnorm returns the norm of each column. If A is a multidimensional array, then vecnorm returns the norm along the first array dimension whose size does not equal 1. Binary function to apply, specified as a function handle. fun must be a binary (two-input) element-wise function of the form C = fun(A,B) that accepts arrays A and B with compatible sizes. For more information, see Compatible Array Sizes for Basic Operations. fun must support scalar expansion, such that if . Mar 25, · How does one apply max(0,z) element-wise in a Learn more about matlab MATLAB. @Dev-iL I don't think the question linked counts as a duplicate. Yes, it does have max(x,y) in the question body but it is in a completely different context. That question states that this command will return the array containing the maximum value (which is actually incorrect) whereas this question is about finding the element-wise maxima. When the MATLAB function contains many element-wise operations, arrayfun can provide improved performance when compared to simply executing the MATLAB function directly on the GPU with gpuArray input data. The MATLAB function can be in its own . M = max(A) returns the maximum elements of an array. If A is a vector, then max(A) returns the maximum of A. If A is a matrix, then max(A) is a row vector containing the maximum value of each column. If A is a multidimensional array, then max(A) operates along the first array dimension whose size does not equal 1, treating the elements as vectors. Apr 05, · I'd like to be able to say, count the values by row from z where each specific value is compared to the row value from y. I would expect the following to yield a 2x3 logical that I could perform my sum function on.

You are mistaken. Let's discuss.
