I defined a function;
function [maBar, wBar, alphaBar] = hcEqPt(vBar, c1, c2, c3, c4)
wBar = vBar/0.129;
maBar = (36.6 + 0.106*wBar + c4*(wBar^2))/c3;
alphaBar = (acos(1-(c2*wBar*maBar/c1)) + 0.0252)/ 1.14;
end
[maBar_1, wBar_1, alphaBar_1] = hcEqPt(22, 0.6, 0.095, 47500, 0.0026);
disp("At v=22, ma = %d, w = %d, alpha = %d", maBar_1, wBar_1, alphaBar_1);
When I try to use this function to obtain a values of vBar further in the script it shows an error "Undefined function or variable".
Kindly help.

fprintf('At v=22, ma = %d, w = %d, alpha = %d', maBar_1, wBar_1, alphaBar_1);
function [maBar, wBar, alphaBar] = hcEqPt(vBar, c1, c2, c3, c4)
wBar = vBar/0.129;
maBar = (36.6 + 0.106*wBar + c4*(wBar^2))/c3;
alphaBar = (acos(1-(c2*wBar*maBar/c1)) + 0.0252)/ 1.14;
end
