If you do not specify an output when loading from an ASCII file, the load function creates a variable named after the loaded file (minus any file extension). For example, the command load mydata.dat reads data into a variable named mydata. For example, see Load ASCII File To create the...
Name and extension of the file to import, specified as a character vector or a string scalar. Ifimportdatarecognizes the file extension, it calls the MATLAB helper function designed to import the associated file format (such asloadfor MAT-files orxlsreadfor spreadsheets). Otherwise,importdatainterp...
Now, create the signal data using the sin function. The sample values you load using the From File block must not contain NaN, Inf, or -Inf values. data = sin(2*pi/3*time); Load timeseries Data Simulink® loading and logging both commonly use timeseries objects to pass time series...
function foo %#function ClassificationSVM load('svm-classifier.mat'); num_dimensions = size(svm_model.PredictorNames, 2); end %function foo In this example, an object from the classClassificationSVMis loaded from a MAT-file. For more information, seeInclude and Access Files in Packaged Applica...
工作区分基本工作区(Base Workspace)和函数工作区(Function Workspace),函数工作区一般在函数调用过程中产生,我们一般接触的就是基本工作区。基本工作区中的变量在关闭Matlab前都不会自动清除,除非用clear命令,所以如果想让程序不依赖于历史数据的话,最好在运行程序前执行“clear all”命令。参考Matlab R2014a帮助文档...
LOAD/SAVE 主要的high level file I/O routines 是LOAD和SAVE函数。LOAD 可以读MAT-file data或者用空格间隔的格式相似的ASCII data. SAVE可以将MATLAB变量写入MAT-file格式或者空格间隔的ASCII data。大多数情况下,语法相当简单。下面的例子用到数值由空格间隔的ASCII filesample_file.txt: ...
vision.labeleler.load.PointCloudSequenceSource类。该方法将sourceName设置为在对话框的文件夹名称参数中输入的名称,将sourceParams设置为一个空结构。如果将Timestamps参数设置为From Workspace并加载了时间戳,那么 应用程序用这些时间戳填充这个结构。 function [sourceName, sourceParams] = getLoadPanelData(this);so...

● load:如果matlab.mat文件存在,导入matlab.mat中的所有变量,如果不存在,则返回error。 ● load filename:将filename中的全部变量导入到工作区中。 ● load filename X Y Z …:将filename中的变量X、Y、Z等导入到工作区中,如果是MAT文件,在指定变量时可以使用通配符“*”。
This example shows how to replace theaddMixedTypesfunction name in the MATLABshrlibsamplelibrary with an alias name,addTypes. To define the alias name, create a prototype file then load the library using the prototype file as the header file. ...
