Linear Function Defined from Two Points (x1,y1) and (x2,y2)Demetris T. Christopoulos
In linear optimization we minimize a linear function given a set of linear constraints. For example, we may wish to minimize a linear function \[x_1 + 2 x_2 - x_3\] under the constraints that \[x_1 + x_2 + x_3 = 1, \quad x_1, x_2, x_3 \geq 0.\] The function we ...

The link functionFLcalculatesf(µ). The derivative of the link functionFDcalculatesdf(µ)/dµ. The inverse functionFIcalculatesg(Xb) =µ. You can specify a custom link function in either of two equivalent ways. Each way contains function handles that accept a single array of values re...
Simple linear regression is a function that allows an analyst or statistician to make predictions about one variable based on the information that is known about another variable. Linear regression can only be used when one has two continuous variables—an independent variable and a dependent variable...
when a training example from the training data set is read, the corresponding example weight is adjusted so that the dual loss function is optimized with respect to the current example. No learning rate is needed by SDCA to determine step size as is required by various gradient descent methods...
Alinear parameter-varying(LPV) system is a linear state-space model whose dynamics vary as a function of certain time-varying parameters calledscheduling parameters. In MATLAB®, an LPV model is represented in a state-space form using coefficients that are parameter dependent. ...
This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject. (Inherited from DependencyObject) CreateInstance() Initializes a new instance of the Freezable class. (Inherited from Freezable) ...
To solve a standard linear programming maximization problem, tap the LP-button in the opening screen. Enter the objective function P: tap the box below A; enter a number using the number pad. Repeat this using the box below B. Tap P to input. Tap the Max-button or the Min-button. En...
