MATLAB中Find函数使用方法 find函数 k = find(X)返回一个向量，其中包含数组X中每个非零元素的线性索引。如果X是一个向量，那么find返回一个与X方向相同的向量。如果X是一个多维数组，那么find返回结果的线性索引的列向量。

k = find(X) returns the indices of the array X that point to nonzero elements. If none is found, find returns an empty matrix. [i,j] = find(X) returns the row and column indices of the nonzero entries in the matrix X. This is R = find(X) R = find (X, n) R = find (X, n,direction) [row, col] = find [row, col, v] = find Description of Find in Matlab. Below will learn all the Find function in Matlab one by one accordingly: 1. R = find(A) Here A is an array, this function will return a vector that will contain linear indices of each non zero elements of A. FindMatlab¶. Finds Matlab or Matlab Compiler Runtime (MCR) and provides Matlab tools, libraries and compilers to CMake.

k = find (X,n,direction) は、 direction が 'last' の場合、 X 内の非ゼロ要素に対応するインデックスを最後から数えて n 個検出します。. direction の既定値は 'first' であり、非ゼロ要素に対応するインデックスを最初から数えて n 個検出します。. 例. [row,col] = find ( ___) は前述の構文に示した任意の入力引数を使用して、配列 X 内にある個々の非ゼロ要素の行と列の添字を返します Find the logical OR of two matrices.

I have the following plot and a file of the data which creates that plot. I would like to have Matlab find the following points for me: [y,x] for peak noted by the 100% line [x] for where the plot crosses the y=0 line [x] for where y is 50% and 20% of the peak found in part 1. To find the derivatives of f, g and h in Matlab using the syms function, here is how the code will look like syms x f = cos(8*x) g = sin(5*x)*exp(x) h =(2*x^2+1)/(3*x) diff(f) diff(g) diff(h) Which returns the following ( You can decide to run one diff at a time, to prevent the confusion of having all answers displayed all at the same time )

In MATLAB Online, variable and function renaming preferences are located under MATLAB > Editor/Debugger > MATLAB Language.. Find Text in Multiple File Names or Files. You can find folders and file names that include specified text, or whose contents contain specified text.

For instance, if you want to know where in the index the condition is satisfied: Mtlab's function would be: find(x>2,1) MATLAB中Find函数使用方法 find函数 k = find(X)返回一个向量，其中包含数组X中每个非零元素的线性索引。如果X是一个向量，那么find返回一个与X方向相同的向量。如果X是一个多维数组，那么find返回结果的线性索引的列向量。 Try This Example. View MATLAB Command. Find the root of a function that has an extra parameter. myfun = @ (x,c) cos (c*x); % parameterized function c = 2; % parameter fun = @ (x) myfun (x,c); % function of x alone x = fzero (fun,0.1) x = 0.7854.

Use findall to find the text object for the x -axis label. Unlike findobj, the findall function finds objects even if the HandleVisibility property is set to 'off'. plot (1:10) txt = xlabel ('My x-axis label');

Guru.com is the leading online space for MATLAB freelancers to find work posted by employers, manage projects and get paid.

index = strfind(cellArray,refString); index = find(~cellfun(@isempty,index)); Result: index = 3 5.

John's code accounts for the first argument but not the second. For instance, if you want to know where in the index the condition is satisfied: Mtlab's function would be: find(x>2,1) MATLAB中Find函数使用方法 find函数 k = find(X)返回一个向量，其中包含数组X中每个非零元素的线性索引。如果X是一个向量，那么find返回一个与X方向相同的向量。如果X是一个多维数组，那么find返回结果的线性索引的列向量。 Try This Example.
