Getting this error Invalid value for OPTIONS parameter PopInitRange: must be an array of finite doubles with two rows. New in Matlab and don't know much about ga tool
% Fitness Function
function [y, z] = myFitness(x)
L = 610; % Length
P = 0.00000785; % Density
y = L * P * x(1) * x(2);
z = 1/(1+y);
end
and constrainst code
Constrainst Function
function[c,c_eq] = myConstrainsts(x)
W = 4500; %Design Load
L = 610; %Length
E = 2.1e05;
c = [(1.5 * W * L)/(x(1) * x(2)^2); ((0.375 * W * L^3)/(E * x(1) * x(2)^3))];
c_eq = [];
end

Are you performing a multiobjective optimization? If not, then your fitness function should return a scalar, not two outputs. If so, then you should call gamultiobj, not ga.
