Can MATLAB be changed to single precision "mode"

Hi! I'm reimplementing a compiled FORTRAN code package in MATLAB, and I just discovered that the "original" is doing everything in single precision. Producing results that are "as identical as they can be" to those produced by the basis package has a higher premium than the extra precision provided by MATLAB's default of doing everything in double, so I'm faced with having much of my code wrapped with single() functions, unless there's a way to put MATLAB into single precision "mode" I wasn't able to find searching the help for "single." Thanks!

There is no such mode.
The closest you get is something supported only on some versions under MS Windows. See this thread for hints -- and be sure to notice the strange results that can occur.
See also, though, <http://www.mathworks.com/support/solutions/en/data/1-79FEJH/index.html?product=ML&solution=1-79FEJH> which implies you cannot control the precision of some operations.
