Hi , I'm working on C-MEX files ,using S-Function Builder .... A very basic problem,. I have two input arrays u0[5] and u1[3] and the output is y0[5],. computing the output via for(i=0;i<5;i++) for(k=0;k<3;k++) y0[i] = u0[i]+ u1[k]; //just a test code With this i'm able to create the .dll file for the S-function builder,...but when i give inputs,i get the below error message : "S-function block 'test2sfun/S-Function Builder' does not have mdlSetInputPortDimensionInfo (mdlSetInputPortWidth) and mdlSetOutputPortDimensionInfo (mdlSetOutputPortWidth) methods. Since the block does not follow the default rules, it cannot use Simulink default methods to set its port widths or dimensions. Please update the S-function by adding the above methods. You can find more information about these methods in the 'Writing S-functions' document" Can somebody please tell me wht could be the problem .. Thanks, mittu |

Hi, You have to define the number of inputs in the configuration file before making its as an s-function. I guess, no need to change the defau;lt value of the output.
