WebFeb 25, 2024 · Answers (1) Because, according to the documentation for isvector, "A vector is a two-dimensional array that has a size of 1-by-N or N-by-1". One can obviously make the argument that that is not a good definition of a vector. But the behavior is well documented. Sign in to comment. WebThe filter2 function filters data by taking the 2-D convolution of the input X and the coefficient matrix H rotated 180 degrees. Specifically, filter2 (H,X,shape) is equivalent to conv2 (X,rot90 (H,2),shape). Extended Capabilities C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™. Thread-Based Environment
