How to convert single cell value into an array?

I have a double value of -35.14 saved as a vector of 8 elements uint8 type like this:

array = [90 62 162 85 148 146 65 192]

I can convert the vector into single-cell value using command:

J1=typecast(conf(1:8), 'double');

The result is single-cell value of -35.14, so the operation is correct. The problem occurs when I want to perform an inverse operation, which is to convert the value of -35.14 back into an array of 8 elements. The inverse operation seems to be command:

cast(J1, 'uint8')

Although it doesn't work at all the way I want it. I converts it only to another single-cell value of different type e.g. uint8 instead of 8-elements array.

define conf

typecast(conf(1:8), 'double');
  Undefined function or variable 'conf'.

well, as I said it's this array:

array = [90 62 162 85 148 146 65 192]

if it makes any differency to you the command might be as well:

J1=typecast(array, 'double');

Of course it makes a difference. In computer programming even one character can make all the difference in the world. I immediately thought of the same thing John did.

okay, sorry if I didn't make it clear in the first place. thanks for your interest though.

Not

cast(J1, 'uint8')

but

typecast(J1, 'uint8')

it works! thanks a lot
