Sep 24, 2012 · Consider the two arrays p = [10;20;30;40] and b = [10,20,30,40] (note the semicolon vs. comma) as an example. In this case, p(3) = [] and b(3) = [] will remove the third element from the array entirely, leaving p = [10;20;40] and b = [10,20,40].

clearvars -except keepVariables removes all variables, except for those specified by keepVariables. Use this syntax to keep specific variables and remove all others.

T2 = removevars(T1,vars) deletes the table variables specified by vars and copies the remaining variables to T2. You can specify variables by name, by position, or using logical indices. For example, to remove table variable var3, use T2 = removevars(T1,'var3').

Jan 17, 2021 · In MATLAB, manipulating arrays and matrices can be done much easier than for-loop solutions, in your task, can do find and delete negative value in the array, simply, as follows: Idx_neg = X < 0; % finding X indices corresponding to negative elements X ( Idx_neg ) = []; % removing elements using [] operator Y ( Idx_neg ) = []; % removing ...

Sep 24, 2010 · Here are a couple questions that are very nearly duplicates, since removing array elements is a component of the answers (although other issues are also covered): MATLAB: what's the most elegant (efficient) way to delete known elements in a matrix?, matlab: delete elements from matrix.

Dec 27, 2023 · Sometimes, you may need to remove one or more elements from an array in MATLAB. For example, you may want to delete outliers, remove duplicate values, or filter an array based on certain criteria. In this comprehensive guide, we will explore different methods to remove elements from arrays in MATLAB:

In this lesson, I will show you how to remove an element from an array in Matlab, using a practical example. To begin, create an array containing several elements: Next, remove the third element from the array by typing v (3)= [ ]. The position of the element should be specified within the parentheses (3), immediately following the array name.

The clear function can remove variables that you specify. To remove all except a few specified variables, use clearvars instead. If you clear the handle of a figure or graphics object, the object itself is not removed.

Nov 12, 2013 · 1) For row 1 in the first array, find the row in the second array which has the same first 3 columns. 2) Remove the elements in the second array if the third column in the second array is between the third column in the first array +- the value from the fourth column in …

Apr 7, 2010 · I have for example a=[1 2 3 4 5 6 7 8 9 10]; and I have to delete each 2 following numbers from 3. like at the end it should be a=[1 4 7 10]; How to do this without a for loop.
