### delete a row in matlab

To delete a row in MATLAB, you can use the following syntax:

matlab`A(row,:) = [];`

where `A`

is the matrix or array from which you want to delete the row, and `row`

is the index of the row you want to delete. The `:`

in the second argument means that all columns of the specified row should be deleted.

For example, let’s say you have a matrix `A`

with 3 rows and 4 columns, and you want to delete the second row:

matlab`A = [1 2 3 4; 5 6 7 8; 9 10 11 12]; row = 2; A(row,:) = [];`

After running this code, the matrix `A`

will now have 2 rows and 4 columns:

matlab`A = 1 2 3 4 9 10 11 12`

Note that this method modifies the original matrix `A`

. If you want to keep the original matrix intact and create a new matrix with the row deleted, you can use indexing to extract the rows you want to keep:

matlab`A = [1 2 3 4; 5 6 7 8; 9 10 11 12]; row = 2; A_new = A([1:row-1,row+1:end],:);`

This will create a new matrix `A_new`

with the second row deleted:

matlab`A_new = 1 2 3 4 9 10 11 12`

### Delete column matlab

To delete a column in MATLAB, you can use the following syntax:

matlab`A(:,columnIndex) = [];`

Where `A`

is the matrix or array, and `columnIndex`

is the index of the column that you want to delete.

For example, if you have a matrix `A`

with three columns and you want to delete the second column, you can use the following code:

matlab`A = [1 2 3; 4 5 6; 7 8 9]; columnIndex = 2; A(:,columnIndex) = [];`

After running this code, the matrix `A`

will have two columns:

matlab`A = 1 3 4 6 7 9`

Note that the column at index 2 (containing elements 2, 5, and 8) has been deleted.

### Delete element in array – MATLAB

In MATLAB, you can delete an element from an array using the built-in function `delete`

. The `delete`

function takes two arguments: the array you want to modify, and the index of the element you want to delete.

Here’s an example:

css`A = [1 2 3 4 5]; index_to_delete = 3; % delete the third element A = delete(A, index_to_delete);`

After running this code, the value of `A`

will be `[1 2 4 5]`

, with the third element (the value 3) removed.

Alternatively, you can use indexing to remove an element from an array. Here’s an example:

css`A = [1 2 3 4 5]; index_to_delete = 3; % delete the third element A(index_to_delete) = [];`

After running this code, the value of `A`

will be `[1 2 4 5]`

, with the third element (the value 3) removed.

Note that when using indexing to delete an element from an array, the resulting array may have a different size than the original array. This is because the deleted element is removed from the array, and the remaining elements are shifted to fill the gap.
