HDL Coder one-bit input/output signals
Hi everyone, does anyone know if it is possible to set the data-type of one-bit input and/or output signals to be std_logic_vector(0 DOWNTO 0) rather than the default std_logic when using the HDL Coder in Matlab 2009b? At the moment I'm having to go into the VHDL and manually create a wrapper to change data-types which... 20 Apr 2010 15:56

Passing paraneters from Objective Function to constraints in fmincon
Hello everyone, I am using FMINCON, and I am trying to pass a variable computed in the objective function file to the non linear constraint file. This is because the variable I want to pass is dependent on the design parameter which is being optimized. Both the computed variable and the design parameter are needed i... 20 Apr 2010 15:56

selective loop programming & switch
Hi This might be a very basic programming query, maybe even not specific to MATLAB. I have two of them. 1> How to make a specialized selective loop processing without making the program too complicated. For example R=[ A matrix with 'numberofiteration' number of elements ] J=[]; for m=1: numberofiteration ... 11 May 2010 17:54

Inconsistency computing residual
I've done a nonlinear regression using lsqcurvfit and would like to find my most under-predicted value. The help page for lsqcurvefit shows residuals computed as predicted - observed. In the residual analysis section of the Curve Fitting toolbox help page it has residuals being computed as observed - predi... 20 Apr 2010 15:56
