Description. L = length (X) returns the length of the largest array dimension in X. For vectors, the length is simply the number of elements. For arrays with more dimensions, the length is max (size (X)). The length of an empty array is zero. Radvektor matlab
Accepted Answer. James Tursa on 19 Sep 1. Edited: James Tursa on 19 Sep There are many ways of doing this. E.g., use the ones () function and divide by Or use the zeros () function and add 1/ Or use the repelem () function. Etc. 2 Comments.

Description. The colon is one of the most useful operators in MATLAB ®. It can create vectors, subscript arrays, and specify for iterations. example. x = j:k creates a unit-spaced vector x with elements [j,j+1,j+2,,j+m] where m = fix (k-j). If j and k are both integers, then this is simply [j,j+1,,k]. example. Använd sedan kommandot length för
sz — Array sizerow vector of nonnegative integers. Array size, returned as a row vector of nonnegative integers. Each element of sz represents the length of the corresponding dimension of A. If any element of sz is equal to 0, then A is an empty array. If A is a scalar, then sz is the row vector [1 1]. En vektor x är en
The numel () function returns the number of elements present in a vector or matrix. For example, let’s get the number of elements present in a matrix. See the code below. vector = [1 2 3 4; 1 2 3 4]; len = numel(vector) Output: len = 8. As you can see, the length or number of elements present in the given vector is 8.

LegendString = cell (1,numel (n)); %// Plot every curve and create the corresponding legend text in the loop. hold all for k = 1:numel (n) plot (x,n (k)*y) LegendString {k} = sprintf ('n = %i',n (k)); end %// Display the legend legend (LegendString) Hope this is what you meant. For a one-liner you can use arrayfun with num2str (thanks to. - Vektorlängd, Matrisstorlek, Antal: n,
x = ; ylength = (length (x) - mod (length (x),5))/5; y (1:ylength) = 0; for n= length (x) y (n/5) = sum (x (1:n)); end. Using vectorization, you can write a much more concise MATLAB process. This code shows one way to accomplish the task: x = ; xsums = cumsum (x); y = xsums (length (x));. En vektors längd anger antalet
plot (xvalue,d5); xvalue is a vector of length and d5 is a vector of length Assuming there's a correspondance between these variables except for the first or last value, you can just trim the extra values. This often happens when differentiating, for example. Theme. Copy. plot (xvalue (2:end), d5) % or. plot (xvalue (1:end-1), d5).
