How to save progressive jpeg with Matlab?

Is it possible to save an image as a progressive jpeg from within Matlab? Using imwrite()? Or calling an outside .jar or similar?

Thank you!

I am trying to imwrite() an RGB image I already have in a matrix. If I 'imfinfo()' the JPEG image saved by Matlab, I get:

       CodingMethod: 'Huffman'
      CodingProcess: 'Lossless'

or

       CodingMethod: 'Huffman'
      CodingProcess: 'Sequential'

and I'm looking for a method that would allow me to save Progressive, so the 'imfinfo()' would return:

       CodingMethod: 'Huffman'
      CodingProcess: 'Progressive'
