vssLinearizeSuperBlock

Syntax

[A,B,C,D] = vssLinearizeSuperBlock(mdlfilename,blkname,inputs,outputs)

[A,B,C,D] = vssLinearizeSuperBlock(mdlfilename,blkname,inputs,outputs,tf)

[A,B,C,D] = vssLinearizeSuperBlock(mdlfilename,blkname,inputs,outputs,tf,ctx)

Example

Get q variable from the base. If not found, value 0 is used.

inps = 1; % vector of input port indices considered for linearization
outs = [1,2]; % vector of output port indices considered for linearization
% Modified context
ctx=struct; 
ctx.z0 = 0;
ctx.th0 = 0;
ctx.phi = 0;
model=bdeGetCurrentModel;
superblock = 'pendulum'; % Selected Super block to linearize
[A,B,C,D] = vssLinearizeSuperBlock(model,superblock,inps,outs,0,ctx);
