k = find(X) returns a vector containing the linear indices of each nonzero element in array X. If X is a vector, then find returns a vector with the same orientation as X. If X is a multidimensional array, then find returns a column vector of the linear indices of the result. example.
Find Array Elements That Meet a Condition. This example shows how to filter the elements of an array by applying conditions to the array. For instance, you can examine the even elements in a matrix, find the location of all 0s in a multidimensional array, or replace NaN values in data.
For example, solve(x + 1 == 2, x) solves the equation x + 1 = 2 for x. example S = solve( eqn , var , Name,Value ) uses additional options specified by one or more Name,Value pair arguments.
13 sty 2010 · The easiest way is to find the equations of the two lines and then calculate the intersection. The equation of a line is given by y = mx + b where m is the slope and b is the y-intercept. For one line you have two points which gives two equations.
30 sty 2015 · A vector in MATLAB is defined as an array which has only one dimension with a size greater than one. For example, the array [1,2,3] counts as a vector. There are several operations you can perform with vectors which don't make a lot of sense with other arrays such as matrices.
Intersection of Two Vectors and Their Indices. Create two vectors with values in common. A = [7 1 7 7 4]; B = [7 0 4 4 0]; Find the values common to both A and B, as well as the index vectors ia and ib, such that C = A(ia) and C = B(ib). [C,ia,ib] = intersect(A,B) C = 1×2. 4 7.
Arrays are MATLAB's standard way of representation. That is, even a scalar numerical value (as a = 1) and strings are represented by arrays. One-dimensional arrays (Vectors) A one-dimensional array is a list of scalar values arranged in a row or column. %Row vector: value separated by commas. rowVector = [27, 972, -198273, 0, 712]
