In MATLAB it is easy to find the indices of values that meet a particular condition: >> a = [1,2,3,1,2,3,1,2,3]; >> find (a > 2) % find the indecies where this condition is true [3, 6, 9] % (MATLAB uses 1-based indexing) >> a (find (a > 2)) % get the values at those locations [3, 3, 3] What would be the best way to do this in Python?

A = [5 7 0; 0 2 9; 5 0 0] A = 3×3 5 7 0 0 2 9 5 0 0. B = [6 6 0; 1 3 5; -1 0 0] B = 3×3 6 6 0 1 3 5 -1 0 0. A & B. ans = 3x3 logical array 1 1 0 0 1 1 1 0 0. In previous versions of MATLAB (before R2016b), you can use the “strfind” function.

TF = ismissing (A) returns a logical array that indicates which elements of an array or table contain missing values. The size of TF is the same as the size of A. Standard missing values depend on the data type: NaN for double, single, duration , and calendarDuration. NaT … Calculate absolute "distances" between each array element and the target value. % Temporary "distances" array.

example. TF = ismissing (A) returns a logical array that indicates which elements of an array or table contain missing values. The size of TF is the same as the size of A. Standard missing values depend on the data type: NaN for double, single, duration , and calendarDuration. NaT …

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. You can perform these tasks using a combination of the relational and logical operators. 2020-04-08 example. TF = ismissing (A) returns a logical array that indicates which elements of an array or table contain missing values.

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 )

k = find( X , n )  This MATLAB function returns a vector containing the linear indices of each nonzero element in array X. 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  [i,j] = find(X) returns the row and column indices of the nonzero entries in the matrix X . This is often used with sparse matrices. [i,j,v] = find(X) returns a column   [i,j] = find(X) returns the row and column indices of the nonzero entries in the matrix X .

[k, d] = dsearchn (A,B) "returns the distances, d, to the closest points.

Finding or calculating roots of a polynomial with the ‘roots()’ command in Matlab® is very easy like above. Conclusion. Do not forget to leave your comments and questions about the ‘roots()’ command in Matlab® below. Your feedback is very important for us. This article is prepared for completely educative and informative purposes.

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. Derivative in Matlab. Let’s consider the following examples. Example 1. Example 2.

To find array elements that meet a condition, use find in conjunction with a relational expression. For example, find(X<5) returns the linear indices to the elements in X that are less than 5 . To directly find the elements in X that satisfy the condition X<5 , use X(X<5) . 2020-01-15 find (MATLAB Functions) MATLAB Function Reference.

Find where the line intersects the data on the left and on the right, which will either be another valley or the end of the data. Mark these locations as the outer endpoints of the left and right intervals. Next, find the highest peak in both the left and right intervals. is not valid Matlab syntax, because the surrounding braces are essential. While I expect my code to work with D fluently, when you search for the character '5' instead of the number 5 . But Matlab offers a much faster solution then, see [EDITED] How to use 'find' function in matlab. Learn more about matlab, function, structures, array Introduction to Matlab Root Finding.
