I want to rename/remove a variable in very large MAT file but want to avoid load all the data, modify variables and write all new data to the disk. The MAT file is hundreds GB and load/write all leads to a heavy IO load.댓글 수: 5 이전 댓글 3개 ...
此函数将 mat 文件 ('matFName') 中的变量名称 ('originalVarName') 替换为新的变量名称 ('newVarName')。 用法:RenameVar(matFName, originalVarName, newVarName) 例子: a=1; b=2; c = 3; save('A','a','b','c'); whos('-file','A') --- 名称大小字节类属性一个 1x1 8 双b 1x1...

Port Order— Maps in the order it appears in the file to the corresponding port number. Block Name— Maps by variable name to the corresponding root input port with the matching block name. Signal Name— Maps by variable name to the corresponding root input port with the matc...
Rename the blocks as shown. Model Thermostat Signal. Model the signal from the thermostat with a hysteresis value of 2 degrees Celsius. In the Thermostat subsystem, add a Relay block. Set the Switch on point parameter to 2, and the Switch off point parameter to -2. Connect and rename the...
For objects, assign the variable name in theDiscrete Filter (orQuantized Filter)text box. If you have variables with the same names in your workspace and you want to overwrite them, select theOverwrite Variablescheck box. Click theExportbutton. The Export to a MAT-File dialog box appears. ...
Split bothBMI_DataandBloodPressure. For each variable being split, you must provide a cell array with the correct number of new names. T3 = splitvars(T1,{'Personal_Data','BloodPressure'},...'NewVariableNames',{{'Age','Height','Weight'},{'Systolic','Diastolic'}}); head(T3,3) ...
