Convert code from Matlab to Mathematica

I need to convert some code from Matlab to Mathematica. At some point I have

fspecial('gaussian', 11, 1.5)

I am confused about what will be equivalent to write in Mathematica.

In Matlab I get:

0.0000    0.0000    0.0000    0.0001    0.0002    0.0003    0.0002    0.0001    0.0000    0.0000    0.0000

I need to get the same in Mathematica too. Thank you in advance

According to the matlab documentation, this command creates a correlation kernel for a gaussian filter. In mathematica, you can simply use ImageCorrelate, and pass this kernel as the second argument.
