You can use this attached code to call the controller. It was given to me
by my advisor Dr. Gerald Corzo from UNESCO-IHE.

Hi Solomon,
Many thanks for your response. I tried to use the function you sent me with no success. I am also using HEC-RAS 4.1. Can you post your main Matlab function that is calling the routine “run_ras.m”? I guess I am having a mistake there. Do you have also a Matlab function that runs HEC-RAS and extracts some data?

Many thanks for your help!

Hi all,

Now I am able to run and control HEC-RAS from MATLAB. One of the tricks is that for some reason, you need to work in the C drive. If you work in the network drive it seems that there are some permission issues.

Cheers,
Art

Hello,

My code has such error:

No method ‘Geometry_GetNode’ with matching signature found for class ‘COM.RAS41_HECRASCONTROLLER’.

My code shows below, anybody can help me to solve this?

clc;clear;close all;

ras_file = ‘D:\RasModel\Program\HuaiRiverProject.prj’;

h=actxserver(‘RAS41.HECRASCONTROLLER’);

h.Project_Open(ras_file);

riv=’Huaihe’;
rch=’Middle’;
rs=’116185.3′;
bb=h.Geometry_GetNode(riv,rch,rs);
