When zoom mode is enabled, zoom the view of axes using the cursor, the scroll wheel, or the keyboard. Cursor — To zoom in, position your cursor where you want the center of the axes to be and click. To zoom out, hold Shift and click. To zoom into a rectangular region, click and drag. Description. M = max (A) returns the maximum elements of an array. If A is a matrix, then max (A) is a row vector containing the maximum value of each column of A. If A is a multidimensional array, then max (A) operates along the first dimension of A whose size is greater than 1, treating the elements as vectors.MATLAB measures all units from the lower left corner of the parent object. This property affects the Position property. If you change the Units property, consider returning its value to the default value after completing your computation to avoid affecting other functions that assume the default value.Property and value pairs, specified as Name1=Value1,...,NameN=ValueN, where Name is the property name and Value is the corresponding value.. Each type of object supports a different set of properties.

Set the value of the LineStyleOrder property, and then call the hold function to set the axes hold state to "on" before calling any plotting …When the axis limit modes are (the default), MATLAB uses limits that span the range of the data being displayed and are round numbers. Setting a value for any of the limits also sets the corresponding mode to . Note that high-level plotting functions like reset both the modes and the limits. Specify the Axes objects as inputs to the plotting functions to ensure that the functions plot into a specific subplot. ax1 = subplot (2,1,1); Z = peaks; plot (ax1,Z (1:20,:)) ax2 = subplot (2,1,2); plot (ax2,Z) Modify the axes …Beginning and ending x-coordinates, specified as a two-element vector of the form [x_begin x_end].Together the x and y input arguments determine the endpoints of the line, arrow, double arrow, or text arrow annotation. The annotation extends from the point (x_begin, y_begin) to (x_end, y_end).By default, the units are normalized to the figure. The lower …fplot (funx,funy) plots the curve defined by x = funx (t) and y = funy (t) over the default interval [-5 5] for t. fplot (funx,funy,tinterval) plots over the specified interval.
