Accessing Single Elements To reference a particular element in a matrix, specify its row and column number using the following syntax, where A is the matrix variable. Always specify the row first and column second A(row, column)
Accessing Single Elements To reference a particular element in a matrix, specify its row and column number using the following syntax, where A is the matrix variable. Always specify the row first and column second: A(row, column)
Accessing Single Elements For example, A= magic(4) A 162313 59 11108 7612 414151 you would access the element at row 4, column 2 with A(4, ans 14
Accessing Single Elements For example, A = magic(4) A = 16 2 3 13 5 11 10 8 9 7 6 12 4 14 15 1 you would access the element at row 4, column 2 with A(4, 2) ans = 14
Linear Indexing With MATLAB, you can refer to the elements of a matrix with a single subscript, A(k). MATLAB stores matrices and arrays not in the shape that they appear when displayed in the MATLAB Command Window, but as a single column of elements. This single column is composed of all of the columns from the matrix, each appended to the last For example, A 243 625 8 is actually stored in memory as the sequence 2, 4, 3, 6, 2, 5, 9.8.1

Linear Indexing If you supply more subscripts, MATLAB calculates an index into the storage column based on the dimensions you assigned to the array. For example, assume a two-dimensional array like A has size [d1 d2], where d1 is the number of rows in the array and d2 is the number of columns. If you supply two subscripts(i, D representing row-column indices, the offset is(j-1)*d1+i
