Hi,
I am trying to create an array using a for loop but I keep getting an error
'Index in position 1 is invalid. Array indices must be positive integers or logical values.'
Any ideas how to solve it?
Thanks
Here is my code:
% Calculate coefficients of inversed function
coeff_IC1 = polyfit(y1, x1, 4);coeff_EC1 = polyfit(y2, x2, 4);% Calculate and plot inversed function y = xg(x)
valueExt_IC1 = zeros(3e5, 1);valueP_IC1 = zeros(3e5,1);for p_IC1 = -3e5:0 ext_IC1 = p_IC1 * (coeff_IC1(2) + (coeff_IC1(3) * p_IC1) + (coeff_IC1(4) * p_IC1^2) + (coeff_IC1(5) * p_IC1^3)); valueExt_IC1((p_IC1 + 1), 1) = ext_IC1; valueP_IC1((p_IC1 + 1), 1) = p_IC1;endvalueExt_EC1 = zeros(1.5e5, 1);valueP_EC1 = zeros(1.5e5,1);for p_EC1 = 0:1.5e5 ext_EC1 = p_EC1 *(coeff_EC1(2) + (coeff_EC1(3) * p_EC1) + (coeff_EC1(4) * p_EC1^2) + (coeff_EC1(5) * p_EC1^3)); valueExt_EC1((p_EC1 + 1), 1) = ext_EC1; valueP_EC1((p_EC1 + 1), 1) = p_EC1;end
