%the equation put in Fcn (block)is (-m*g-sgn(u[1]*A*rho*u[1]^2)/m in simulink

%The rest of the code I can work out myself. I need a substitution for Fcn block please.

rhoMaterial =100;
R=.287 % gas constant for air kj/kg;

rhoAir =p/(R*(273+t));%

It is my understanding that you are looking for an alternative to the 'Fcn' block in the R2021a release.
The following documentation suggests the use of 'MATLAB Function' block instead of the 'Fcn' block in the R2021a release:
Please refer to the MATLAB Function Block documentation for more information on the usage of the block.
