using fmincon function for optimisation

Hey, I was wondering if anyone could explain this. I am using fmincon function for optimisation but gets the following error: Error using fmincon (line 220) FMINCON requires the following inputs to be of data type double: 'Aeq','Beq'.

Error in OptimisationCode1 (line 112) [xalpha,fval,flag]=fmincon(gap,xalphakeep,alphamin,alphamax,@nonlconstr,options);

But I believe both alphamin and alphamax are defined as double by default. Could you please suggest any alternatives?

alphamin and alphamax are both matrices defined in the code initially

 [xalpha,fval,flag]=fmincon(gap,xalphakeep,[],[],[],[],alphamin,alphamax,@nonlconstr,options);

alphamin and alphamax must be vectors of size "xalphakeep".

Best wishes
