MATLAB: Saving Multiples Variable of a function

functionvariable

I have some codes that i make

function result = back_prop(W1,W2,W3, A1,A2,A3, T_Input, Output)

dim_A = size(T_Input)

m = dim_A(2)

dZ3 = A3 – Output.'

dW3 = 1/m * dot_mult_dif_dim(dZ3, A2.')

db3 = 1/m * np_sum(dZ3)

dZ2 = dot_mult_dif_dim(W3.', dZ3).*(1 – A2.^2)

dW2 = 1/m * dot_mult_dif_dim(dZ2, A1.')

db2 = 1/m * np_sum(dZ2)

dZ1 = dot_mult_dif_dim(W2.', dZ2).*(1 – A1.^2)

dW1 = 1/m * dot_mult_dif_dim(dZ1, T_Input.')

db1 = 1/m * np_sum(dZ1)

end

where dot_mult_dif_dim and np_sum is a function that i make my own,

how can i save or access dZ3, dW3, db3, dZ2, dW2, db2, dZ1, dW1, and db1 ? each of them are matrix

i want to use them to update some parameters in NN, thank you

If you want to use the variables in the other function, use this command in both functions:

global dZ3 dW3 db3 dZ2 dW2 db2 dZ1 dW1 db1

When saving aw1 in a.m you need to save all other symbolic variables too

save('filename.mat', 'aw1', 'w1', 'w2', 'w3', 'w4', 'v1', 'v2', 'x1', 'x2', 'yd' );

and then load the file in b.m

load('filename.mat');

Alternatively, you can also try to just save aw1

save('filename.mat', 'aw1')

and then in b.m write

load('filename.mat');
syms w1 w2 w3 w4 v1 v2 x1 x2 yd

Hi,

try:

% Sabit degerler
k = 1.38e-23;      % Boltzman sabiti
q = 1.602e-19;     % Elektronun yuku
T = 25+273;        % Sicaklik (K)
Ns = 36;           % Hucre Sayisi
a1 = 2.4;          % Isc
a2 = 21.8;         % Voc
a3 = 17.2;         % Vmpp
a4 = 2.20;         % Impp
a5 = (Ns*k*T)/q;   % Vt
%Is0 = (a1+Ki*dt)/(exp((a2+Kv*dt)/(x3*a5))-1);
x0 = [2.4, 1.2e-7, 1.5, 0.5, 600];
lb = [2, 1e-7, 1.3, 0.3, 400];
ub = [2.6, 5e-7, 1.7, 0.7, 900];
x = lsqnonlin(@(x)myfun(x, a1, a2, a3, a4, a5), x0, lb, ub);
function f = myfun(x, a1, a2, a3, a4, a5)
x1 = x(1);
x2 = x(2);
x3 = x(3);
x4 = x(4);
x5 = x(5);
f(1) = x1-x2*(exp((x4*a1)/(x3*a5))-1)-((x4*a1)/x5)-a1;
f(2) = x2*(exp(a2/(x3*a5))-1)+(a2/x5)-x1;
f(3) = x1-x2*(exp((a3+x4*a4)/(x3*a5))-1)-((a3+x4*a4)/x5)-a4;
f(4) = a3*(((x2/(x3*a5))*exp((a3+x4*a4)/(x3*a5))+(1/x5))/(1+((x4*x2)/(x3*a5))*exp((a3+x4*a4)/(x3*a5))+(x4/x5)))-a4;
f(5) = (((x2/(x3*a5))*exp((x4*a1)/(x3*a5))+(1/x5))/(1+((x4*a1)/(x3*a5))*exp((x4*a1)/(x3*a5))+(x4/x5)))-(1/x5);
end
