Question

In MATLAB, how do you perform indexing in arrays? Additionally, explain how to index specific rows and columns.

a) array(index)
b) array[row, column]
c) array(index, row)
d) array(column, row)

Answer 1

In MATLAB, array indexing is performed using array(index) for individual elements and array(row, column) for specific row and column elements, with MATLAB using one-based indexing.

Step-by-step explanation:

In MATLAB, indexing arrays allows you to access specific elements within an array. For indexing elements, the syntax array(index) is used where index is the position of the element within the array. To index a specific element using row and column numbers, the correct syntax is array(row, column). If you want to access a whole row or column, you can use : in place of row or column number. For example, array(:, column) accesses the entire specified column, and array(row, :) accesses the entire specified row. Note that MATLAB uses one-based indexing, so the index starts at 1.
