![]() ![]() linspace is similar to the colon operator, :, but gives direct control over the number of points and always includes the. The spacing between the points is (x2-x1)/ (n-1). Caution: A is the conjugate transpose and the plain transpose is A. y linspace (x1,x2) returns a row vector of 100 evenly spaced points between x1 and x2. HDL Code Generation Generate VHDL, Verilog and SystemVerilog code for FPGA and ASIC designs using HDL Coder. GPU Code Generation Generate CUDA® code for NVIDIA® GPUs using GPU Coder. A (:) Or if you are sure that A is a row vector, Theme. C/C++ Code Generation Generate C and C++ code using MATLAB® Coder. Σ 1 = σ x = ( 0 1 1 0 ) σ 2 = σ y = ( 0 − i i 0 ) σ 3 = σ z = ( 1 0 0 − 1 ) is Hermitian and traceless. For any kind of array you get a single column vector by. One easy improvement is to broadcast the first line in your loop to avoid allocating a matrix for (sparseR + reshape(q' * sparseS, 199, 199)) and then another one for 0.5 * 0.05 * (sparseR + reshape(q' * sparseS, 199, 199)): tmp = 0.5. Modifying your code to pre-allocate those matrices may help a lot. In particular, you are constructing new matrices to hold a lot of intermediate quantities. You are seeing a lot of allocations because your code really does allocate a lot of memory. Running your code in a function, I see 3.699408 seconds (41.60 k allocations: 3.787 GiB, 5.39% gc time) which is already quite close to what you reported MATLAB as giving. Instead, put the code you’re timing in a function. If A is a multidimensional array, then sum(A) operates along the first array dimension whose size is greater than 1, treating the elements as vectors. If A is a matrix, then sum(A) returns a row vector containing the sum of each column. ![]()
