Find first index matlab
WebThe Syntax that we will use in MATLAB is: a = X (2, 3) The Output that we obtain will be a single value present at the position (2, 3) in the array X. i.e, Output is 7 This is how our input and output will look like in MATLAB console: Input: X = [0 2 4 6; 1 3 7 9; 8 1 11 2; 13 4 0 6] a = X (2, 3) Output: Webk = find (X,n,direction), donde direction es 'last', encuentra los últimos n índices correspondientes a los elementos distintos de cero de X.

WebMar 21, 2016 · 1 Answer Sorted by: 3 The index is easily obtained with the second output of max. The value can be found from that index using sub2ind or computing the corresponding linear index manually. To return a different index in columns that contain all NaN, use the first output of max to detect that situation and change the result for those columns. WebTo 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) . Find the index of each letter.
