I am trying to edit the SAM generated MATLAB code. Such that I create script
(SIF) of mine separately with inputs I want to change on the Sam MATLAB function file.
Aimed to enable making calculations for some properties outside SAM and return the values to the SAM code.
I have created a
matfile.Obj which reads the .mat code generated from the script file
(SIF).
However, when I make the necessary changes to the SAM code it doesn't seem to give the same results prior to the changes.
To clarify, examples of some changes:
In
SIF.m file
sys_cap = % Nameplate capacity
RFA= 513.6 %Reflective aperture area m^2
Dvar = 7 %Design turbine gross output MW
DNI_des = 950 % Design point solar irradiation W/m^2
are all stored to a
SIF.mat file and a matfileObj is created ==> matfileObj = matfile ('SIF.mat'); to read and obtain the variables as needed. using
b= matfileObj.sys_cap;
ssccall('data_set_number', data, 'system_capacity', 'b');
j= matfileObj.I_bn_des;
ssccall('data_set_number', data, 'I_bn_des', 'j');
A_aperture =[ matfileObj.RFA ; matfileObj.RFA ];
ssccall( 'data_set_matrix', data, 'A_aperture', A_aperture );
etc
While the command for matfileObj seem to work correctly. The SAM function code appears to give wrong results.
N.B: Changing the number directly in the SAM code appears to work fine. Also I tried changing the ssccall command for number to array (i.e. 'data_set_number' to either 'data_set_array' or 'data_set_matrix') but as expected it did not work due to the code constraints
tcslinear_fresnel errors:
precheck input: variable 'demand_var' (<array>) of wrong type, <number> required.
tcslinear_fresnel errors:
precheck input: variable 'demand_var' (<matrix>) of wrong type, <number> required.
I have also added the edited code.
