find:Find indices and values of nonzero elements,常用的搜索定位计数函数。 find的用法较多,比较常用的如下: find(X) :寻找数组X中不为0的元素,并返回其索引数(其索引数是按照如图所示的顺序索引的)。 matlab中元素索引顺序 find(~X):寻找数组X中为0的元素,若不存在为0的元素则返回空矩阵。
This code creates two arrays, A and B, and concatenates them horizontally into array C using the comma operator [ ]. Method 2: Vertical Concatenation MATLAB’s [ ; ] operator vertically concatenates arrays by stacking them on top of each other. This is helpful if you want to vertically mer...
means B is the transpose of A; C=A(:), means to arrange the elements of matrix A vertically from top to bottom and from left to right. D=inv(A), means to find the inverse of matrix A, and the matrix A must be a square matrix. ...
MATLAB operates primarily on arrays and matrices, both in whole and in part. A matrix is a two-dimensional array often used for linear algebra. Array Indexing Variables in MATLAB are typically arrays that can hold many numbers. When you want to access selected elements of an array, use index...
nonlcon is a function that accepts a vector or array x and returns two arrays, c(x) and ceq(x). c(x) is the array of nonlinear inequality constraints at x. fmincon attempts to satisfy c(x) <= 0 for all entries of c. ceq(x) is the array of nonlinear equality constraints at x....

MATLABis an abbreviation for "matrix laboratory."(matrix laboratory矩阵实验室) While other programming languages mostly work with numbers one at a time, MATLAB®is designed to operate primarily on whole matrices and arrays. All MATLAB variables are multidimensionalarrays, no matter what type of dat...
In this MATLAB program, we start by creating two cell arrays `x` and `y` containing strings as their elements. Next, we run a `for` loop to compare the corresponding elements of the two arrays. If the strings in the two cell arrays at a specific index are equal, the code displays ...
Element-by-element division of a and b:b(i,j)/a(i,j). Both arrays must be the same shape, or one of them must be a scalar. Matrix division defined by ab . Matrix division defined by a b . Element-by-element exponentiation of a and b:...
