Dear
Did you solve this problem ?
I also had this problem recently. "An error occurred while propagating data type 'double' through 'adrc/cg_adrc'". (the last problem in the attached picture 'erroes.JPG')
Hope you can help me if possible. Thank you.

You need to preallocate the output variable and assign into the appropriate locations in it, instead of dynamically growing your array.

Maybe you want something like,
function [xfar_in,yfar_in] = fartheta(y_veh,x_veh,error_in)
nveh = length(x_veh);
x_save = zeros(1, nveh);
y_save = zeros(1, nveh);
for i = 1:nveh
xin_new = x_veh(i);
yin_new = y_veh(i);
error_in = 0.001;
while true
xin_new = xin_new + 0.01;
yin_new = 1*sin(2*pi*xin_new/25);
slope_in = (yin_new-y_veh(i)) ./ (xin_new-x_veh(i));
slope_curve_in = (1*2*pi/25)*cos(2*pi*xin_new/25);
error_in = slope_curve_in-slope_in;
if error_in <= 0
break;
end
xin_new = xin_new+0.01;
end
x_save(1,i) = xin_new;
y_save(1,i) = yin_new;
end
and here calculate xfar_in and yfar_in
