This MATLAB function returns a vector containing the linear indices of each nonzero element in array X. I would get the index of elements of g_vector that have their index in list matrix setted to 0. How can I do? If I do. g_counter(list == 0). I get 0 element of g_vector When you index into the matrix A using only one subscript, MATLAB treats A as if its elements were strung out in a long column vector, by going down the May 23, 2019 This is just an example. I want to learn how to find index of a(n). The "min" and "max" functions in MATLAB return the index of the minimum and maximum values, respectively, as an optional second output argument. Old thread, but here's one way to do it if you input a vector instead of an array. If you have an odd number of values, this will find the index of the first entry of the
How can I index a MATLAB array returned by a function without first assigning it to a local variable? Ask Question Asked 9 years, 2 months ago. MATLAB complains about Unbalanced or unexpected parenthesis or bracket on the first but you have to use the functional form of the indexing operator. When you perform an indexing operation
How I can find index of element in array?. Learn more about indexing, array, machine learning examples I'm trying to write a script in MATLAB that finds the location of the minimum value of a 2D array of numbers. I am certain there is only 1 minimum in this array, so having multiple locations in the array with the same minimum value is not an issue.

Indexing Arrays. Indexing into Matlab arrays is very often glossed over, but it is actually quite a powerful (and fast) technique. There are a surprising number of things that can be done by just indexing into a Matlab array. These indexing tricks come in handy to avoid "for" loops and in vectorizing code.

When you perform an indexing operation However, we have repeated the element 3 index. So the computed right-hand side has element 1 and 2 copies of the updated element 3 - updated each in the same way, since that's what the code says to do. Remember I said that the MATLAB behavior is as if we placed the right-hand side into a temporary array.

Index = strfind(Mycellarray, 'Bla');. I get the following error: ??? Error using ==> cell.strfind at 35 If any of the input arguments are I need to find the index of those whose value is greater than 1 and less than 5. how to do this? 0 Comments.

A linear index allows use of a single subscript to index into an array, such as A(k).MATLAB ® treats the array as a single column vector with each column appended to the bottom of the previous column. Thus, linear indexing numbers the elements in the columns from top to bottom, left to right. Indexing into a matrix is a means of selecting a subset of elements from the matrix. MATLAB ® has several indexing styles that are not only powerful and flexible, but also readable and expressive. Indexing is a key to the effectiveness of MATLAB at capturing matrix-oriented ideas in understandable computer programs. Indexing with a Single Index. Another method for accessing elements of an array is to use only a single index, regardless of the size or dimensions of the array. This method is known as linear indexing. While MATLAB displays arrays according to their defined sizes and shapes, they are actually stored in memory as a single column of elements. Indexing: vectors in MATLAB are not the same as in every other programming language because the indexing starts from one instead of zero, which means that the first value has the index one. Column Vector: to define a column vector, you can either separate every element with a semi-colon (;), or you can define the vector and use the transpose function, as we will see in the following sections:
