In MATHEMATICA, WorkingPrecision is an option for various numerical operations that specify the number of digits of precision that should be maintained in internal computations. Is there anything like it in MATLAB?
I am interested in running certain codes using a few significant digits maintained in internal computations like say 3 or 4 digits only, so is this possible?

Yes, if you have access to Symbolic Math Toolbox. See https://www.mathworks.com/help/symbolic/vpa.html. Otherwise, you will get double-precision math, which has about 16 digits accuracy.
