function [calc_valid, EM] = input_check(N,t,S,EV)
inputs = [N,t,S,EV]; %The inputs are placed in a vector.
calc_valid = 0;
if isreal(inputs)==0 || isa(inputs,'numeric')==0 %This checks if other than real numbers and numbers are inputted.
EM = 'ERROR: The inputs are not real numbers.';
elseif N~=0 && N<1 || N>8000 %This checks if N is not within the range 1:8000 or not = 0.
EM = 'ERROR: N is not within the range 1:8000';
elseif t~=0 && t<(1/8000) || t>2 %This checks if t is not within the range 1/8000:2 or not = 0.
EM = 'ERROR: t is not within the range 1/8000:2';
elseif S~=0 && S<25 || S>51200 %This checks if S is not within the range 25:51200 or not = 0.
EM = 'ERROR: S is not within the range 25:51200';
elseif EV<-6 || EV>23 %This checks if EV is not within the range -6:23.
EM = 'ERROR: EV is not within the range -6:23';
elseif N==0 && t==0 || N==0 && S==0 || t==0 && S==0
EM = 'ERROR: Only EV and one other variable are permitted to be zero';
else
EM = '';
calc_valid = 1;
end
end
For some reason all the other checks work except isreal ?
