To directly find the elements in x that satisfy the condition x 5 use x x 5 avoid function calls like x find x 5 which unnecessarily use find on a logical matrix.
Find a value in an array matlab.
You can use the find function to return the positions corresponding to an array element value.
In python i can use.
This example shows how to filter the elements of an array by applying conditions to the array.
Generally to generate a multidimensional array we first create a two dimensional array and extend it.
But if you want to extract row and column you just need to adapt the code jan gave you.
The linear index of 5 is 4 not 5.
Linearindices find a 8 linearindices 2 3.
Using length is a really bad idea.
I know that number for example 5 is an element in array x but i don t know it s index.
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.
A 7 8 8 2 5 6.
Store the row and column return from find and put it in the match cell array.
You can perform these tasks using a combination of the relational and logical operators.
An array having more than two dimensions is called a multidimensional array in matlab.
Ismember will return an array of 1 or 0 depending on if the cell value there is or isn t the value you re searching for.
Whoever wrote that template has done a lot of beginners a disservice by teaching them to use a function that would be better replaced by numel or size in this case numel would be much better and would actually loop over all elements of the input array.
For example let s create a two dimensional array a.
Octave 9 x x 2 2 3 4 3 2 6 4 8 octave 10 ismember x 4 ans 0 1 0 0 0 1 0 0 0 and then you can use find and ind2sub to get the array indicies of the 1s.
This example shows how to filter the elements of an array by applying conditions to the array.
Multidimensional arrays in matlab are an extension of the normal two dimensional matrix.
For example find x 5 returns the linear indices to the elements in x that are less than 5.
