please show how the process should be done in matlab, please show codes

Create the following matrices and use them in the exercises that follow. A=45928120861771545309214435114B=[43952]C=328547 a) (10\%) Create a submatrix named D from A, without tho first row and first column. b) (10\%) Combine vector B and vector C to creato a elngle matrlx named E with 2 rows and 6 columna. Replace any missing values with zero. c) (10\%) Create a matrix H with 4 rows and 60 columns and with values starting from 0 to . d) (5\%) Save all the matrices created to a flie, clear the workspace and load only matrix H from the fllo
