WebFeb 16, 2024 · To approximate a numeric value in double precision, you can use the “double” function. For example: Theme Copy val = double (sqrt (2)) 1.4142 If your expression uses a symbolic variable, you can use the “vpa” function. “vpa” gives a numerical approximation to the value (32 digits by default). For example: Theme Copy syms x val = vpa (sqrt (2)*x) WebNov 4, 2024 · If so call vpa with two inputs, the first this array and the second the number of digits you want to use to display the array. Alternately convert this array (since it contains no symbolic variables) to a double precision array using double then it will respond to the format command. Michael Croucher on 3 Nov 2024
