Problem with the class of my data

 Hello, I am working with images and using 'deconvreg','deconvblind','deconvvwnr','deconvlucy'.
 My images are '.bmp', so the matrix which I'm working are of the class 'uint8'.
 If I work with the default values of DAMPAR, WEIGHT, ecc... it's ok, but when I want to change these I have always the same error, because DAMPAR or WEIGHT  are double and they have to be of the same class of the matrix (I have been searching and I found this: I and PSF can be uint8, uint16, int16, double,or single. DAMPAR and READOUT musthave the same class as the input image. Other inputs have to  be double.The output image J (or the first array of the outputcell) has the same class as the input image I)
 The problem come when I change the class, using 'uint8', for example: 

x=8; %double
 x=uint8(x)
 x=8        %now x's class is uint8. That's ok
 y=8.3
 y=uint8(y)
 y=8       *%THIS IS THE PROBLEM*

For working with deconvlucy and the WEIGHT, I could work with values from 0.0 to 1, but I lose the decimals if I changed to uint8 class. What can I do? (change the class of the matrix could be a disaster, I think, because this part it's a little part of my program)

Just cast (the badly-named) "I" to be a double before using it in any convolution routine.

Ok. Thank you. I have to do it. Thank you again
