my code is:

a = 20000;

R = 0.06;

n = 180;

r = R/12;

z = amortization(a,R,n);

for i = 1:180

b = a*r;

%b is interest payed in first month

c = z-b;

%c is amount applied towards loan principle

a = a-c;

%a is new amount left to be paid

array2table(a)

end

I want to be able to save all the a values from previous iterations and plot them against i(1:180). As of right now my code is overwriting my a value and only producing one output instead of saving all values of a. Please help I am new to Matlab.

在 MATLAB Online 中打开

n = 180 ; 
a = zeros(1,n) ; 
a(1) = 20000;
R = 0.06;
r = R/12;
z = amortization(a(1),R,n);
for i = 2:n
    b = a(i-1)*r;
    % b is interest payed in first month
    c = z-b;
    % c is amount applied towards loan principle
    a(i) = a(i-1)-c;
    %a is new amount left to  be paid    
end
