KALMAN applies kalman filtering to a discrete ssm with given i/o %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: KALMAN applies kalman filtering to a discrete ssm with given i/o. CALL: [mat_out pl_out] = kalman(sys, plist_inputs) INPUTS: - sys, (array of) ssm object OUTPUTS: _ mat_out contains specified returned aos _ pl_out contains 'lastX', the last state position Parameters Description %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

| COVARIANCE VARIABLE NAMES | {} [0x0] | none | A cell-array of strings specifying the desired input variable names. |
| CPSD VARIABLE NAMES | {} [0x0] | none | A cell-array of strings specifying the desired input variable names. |
| AOS VARIABLE NAMES, AO NAMES, AO PORT NAMES | {} [0x0] | none | A cell-array of input port names corresponding to the different input AOs. |
| CONSTANT VARIABLE NAMES | {} [0x0] | none | A cell-array of strings of the desired input variable names. |
| RETURN STATES | {} [0x0] | none | A cell-array of names of state ports to return. |
| RETURN OUTPUTS, OUTPUTS | {} [0x0] | none | A cell-array of output ports to return. |
| KNOWN OUTPUT VARIABLE NAMES | {} [0x0] | none | A cell-array of strings of the known output variable names. |

| COVARIANCE | [] | none | The covariance of this noise between input ports for the time-discrete noise model. |
| CPSD | [] | none | The one sided cross-psd of the white noise between input ports. |
| AOS | [] | none | An array of input AOs (experimental stimuli). |
| CONSTANTS | [] | none | Array of DC values for the different corresponding inputs. |
| KNOWN OUTPUTS | [] | none | Array of AOs for the different corresponding outputs (experiment measurements). |
| NSAMPLES | Inf | none | The maximum number of samples to simulate (AO length(s) overide this). |
| SSINI | {} [0x0] | none | A cell-array of vectors that give the initial position for simulation. |
| TINI | 0 | none | The initial filtering time (seconds). |
| DISPLAYTIME | 1 |
|
Switch off/on the display |
| REORGANIZE | 1 |
|
When set to 0, this means the ssm does not need be modified to match the requested i/o. Faster but dangerous! |
| FORCE COMPLETE | 0 |
|
Force the use of the complete simulation code. |
