Q = cumtrapz (Y) computes the approximate cumulative integral of Y via the trapezoidal method with unit spacing. The size of Y determines the dimension to integrate along: If Y is a vector, then cumtrapz (Y) is the cumulative integral of Y. If Y is a matrix, then cumtrapz (Y) is the cumulative integral over each column.

both for equally and unequally spaced points, is the trapezoidal rule. The ... machine accuracy, or the cumulative error involved in using many tiny inter-.

Cumulative trapezoidal numerical integration Syntax Z = cumtrapz(Y) Z = cumtrapz(X,Y) Z = cumtrapz(... dim) Description Z = cumtrapz(Y) (This is similar to cumsum(Y), except that trapezoidal approximation is used.) To compute the integral with other than unit spacing, multiply Zby the spacing increment.

In mathematics, and more specifically in numerical analysis, the trapezoidal rule (also known as the trapezoid rule or trapezium rule; see Trapezoid for more information on terminology) is a technique for approximating the definite integral. The trapezoidal rule works by approximating the region under the graph of the …

Z = cumtrapz (X,Y) computes the cumulative integral of Y with respect to X using trapezoidal integration. X and Y must be vectors of the same length, or X must be a column vector and Y an array whose first nonsingleton dimension is length (X). cumtrapz operates across this dimension.

One can compute the trapezoidal numerical integration using the ... a vector or matrix's cumulative trapezoidal numerical integration.

Cumulative trapezoidal numerical integration Syntax Z = cumtrapz (Y) Z = cumtrapz (X,Y) Z = cumtrapz (... dim) Description Z = cumtrapz (Y) computes an approximation of the cumulative integral of Y via the trapezoidal method with unit spacing. To compute the integral with other than unit spacing, multiply Z by the spacing increment.

Q = cumtrapz (X,Y) integrates Y with respect to the coordinates or scalar spacing specified by X. If X is a vector of coordinates, then length (X) must be equal to the size of the first dimension of Y whose size does not equal 1. If X is a scalar spacing, then cumtrapz (X,Y) is equivalent to X*cumtrapz (Y). example.

Cumulatively integrate y(x) using the composite trapezoidal rule. ... The result of cumulative integration of y along axis. If initial is None, ...

Cumulative trapezoidal numerical integration ... computes an approximation of the cumulative integral of Y via the trapezoidal method with unit spacing.

Q = cumtrapz (Y) Q = 1×5 0 2.5000 9.0000 21.5000 42.0000. This approximate integration yields a final value of 42. In this case, the exact answer is a little less, 41 1 3. . The cumtrapz function overestimates the value of the integral because f (x) is concave up.

Cumulative trapezoidal numerical integration Introduced before R2006a Description Q = cumtrapz (Y) computes the approximate cumulative integral of Y via the trapezoidal method with unit spacing. The size of Y determines the dimension to integrate along: If Y is a vector, then cumtrapz (Y) is the cumulative integral of Y.

Q = cumtrapz (X,Y) integrates Y with respect to the coordinates or scalar spacing specified by X. If X is a vector of coordinates, then length (X) must be equal to the size of the first dimension of Y whose size does not equal 1. If X is a scalar spacing, then cumtrapz (X,Y) is equivalent to X*cumtrapz (Y). example.
