1/23/2024 0 Comments Matlab repmat![]() ![]() B repmat (A,r1.,rN) especifica una lista de escalares, r1.,rN, que describe cmo se disponen las copias de A en cada dimensin. El tamao de B es size (A)n cuando A es una matriz. The syntax is simple: repmat (A, m, n), where A is the input matrix, and m and n are the. Give it a matrix, and it will replicate it as many times as you want, either horizontally, vertically, or both. I know one can use array comprehensions to create such arrays but it’s not as intuitive/compact. B repmat (A,n) devuelve un arreglo que contiene n copias de A en las dimensiones de fila y de columna. Now, let's talk about the star of the show - the 'repmat' function. Also, I’m not sure why Julia doesn’t copy the value at all locations as MATLAB’s repmat does? Of course, for immutable structures this issue doesn’t exist. ![]() IMO, this makes fill and repeat less useful in practice. Repeat, albeit a different function with a different goal, can also have the same behavior. This behavior can be confusing, especially for beginners, when one tries to mutate a single location, it will silently modify all locations similarly. However, if this vaule is a mutable object, fill will place that very same object at all locations. Repeat a 0-D to 2-D array or matrix MxN times. ![]() If you run the command clear before running the script again you will find that the plot command will fail.Fill is very useful for creating arrays having the same vaule at all locations. The reason the code still worked is probably that the previous value of Y was still stored in the workspace. If you comment out Y then Y isn't defined. Which plots two vertical lines, one and two standard deviations from the mean. Is equivalent to plot(,, 'g','LineWidth',2) When plot is called it plots one line per column of the X and Y matrices. Together you end up with X = [mu3+1*sigma3, mu3+2*sigma3 First create a row vector containing one and two standard deviations from the mean. X repmat (mu3+ (1:2)sigma3,2,1) is equivalent to. The logic is similar for the Y matrix except it repeats in the column direction. Lets break the expression into multiple statements. Show -1 older comments Hide -1 older comments. I have a vector with a length of 1023 elements (1 by 1023 elements). % To help understand how repmat works, if we had X = repmat(xval,3,2) we would get Learn more about matrix, vector, matrix manipulation MATLAB. % lines so the first and second point should be equal so we just use repmat to repeat them. Use logical switches to plot the function. % Repeat the matrix twice in the vertical dimension. Use MATLABs repmat function to plot a discrete sequence with 6 repetitions of (o, 1, 2, 3, 4), starting at n 0. repmat(x, nk, 1) K repmat(k', 1, nx) where the function repmat was used in lines 5-6 of Example0106.m (page 25) and explained in 1.611-12 (pages 26. Web browsers do not support MATLAB commands. Run the command by entering it in the MATLAB Command Window. B repmat(A,M N) accomplishes the same result as repmat(A,M,N). ![]() Is equivalent to % First create a row vector containing one and two standard deviations from the mean. B repmat(A,M,N) creates a large matrix B consisting of an M-by-N tiling of copies of A. Lets break the expression into multiple statements X = repmat(mu3+(1:2)*sigma3,2,1) ![]()
