Matlab provides a wide range of graphics facilities which may be called from within a script or used simply in command mode for direct execution. We begin by considering the plot function. This function takes several forms. For example, plot(x,y) plots the vector x against y. If x and ...
In MATLAB, there are two types of code files, scripts and functions. If the first executable line of your code file is a function definition like you have in the code above, then your file is a function.Therefore
ginput - graphical input from mouse or cursor this matlab function enables you to identify n points from the current axes and returns their x- and y-coordinates in the x and y column vector 24、s. uiimport - import data interactively this matlab function opens a dialog to interactively load...
% The six-row by one-column c matrix is defined below. % The entries in the full $2 \times 2$ a matrix and the $2 \times 1$ f vector % follow directly from the definition of the % two-equation system shown above. % c = [1; 0; 1; D; 0; D]; a = [0; 0; 1; 0];...
I'm reading in a 5x5 matrix from excel and a 1x5 vector from excel. I then need to multiply them together in a function. Unfortunately it must be in a function. I keep getting an error message of "Error: Function definitions are not permitted in t...
It is never valid to copy and paste a "function" definition to the command line. It is also not valid to eval() a character vector that contains a "function" definition. In releases up to R2015a, it was never valid to have a "function" definition inside a script file (a...
Error using VectorAngle Unable to update the class 'VectorAngle' because the new definition contains an error: Undefined function or variable 'vx'. 类方法中的表达式 类方法中的表达式的执行方式与任何函数中的表达式一样。当方法执行时,MATLAB 计算函数工作区中的表达式。因此,类方法中使用的表达式不被视为...
model.MC.interfaceNormals [-] A 2D array of dimension (2 x (nxnynz)) where local interface normal vector angles are stored. Each column contains the theta, phi angles for one voxel's interface normal vector. Used for calculated of refraction and reflection on oblique and curved interfaces ...
The function imshow can also be accompanied by a two-element vector [low high] with which the user specifies the display range of the grey-scale image. If this vector is left empty [], the minimum and maximum grey-scale values of the image are displayed as black and white pixels, respec...
Upon executing the dsolve function using the code provided below, I receive the error message, "Invalid indexing or function definition. Indexing must follow MATLAB indexing. Function arguments must be symbolic variables, and function body must be sym expression."...
