Pass data type to function.

I have an image, i have read it and want to pass the image data type "unit 8" to function, which is used in case statment.

while printing the 'origClass' it contains the char and i have to pass the 'unit8', which is data type of the read image.

buf = hTile.buf;
[tile_size_y, tile_size_x, numComponents] = size(buf);
origClass = class(buf);
switch origClass
    case {'unit8'}
        inputRGB = zeros(tile_size_y, tile_size_x, numComponents, 'int8');
    case {'uint16'}
        inputRGB = zeros(tile_size_y, tile_size_x, numComponents, 'int16');
            case {'uint32', 'single'}
        inputRGB = zeros(tile_size_y, tile_size_x, numComponents, 'int32');
 end
