Open the example CDF, and then get the name of a variable in the file: cdfId = cdflib.open("example.cdf"); name = cdflib.getVarName(cdfId,1) name = 'Longitude' % Clean upcdflib.close(cdfId) clearcdfId Tips This
Avoid creating variables with the same name as a function (such as i, j, mode, char, size, and path). In general, variable names take precedence over function names. If you create a variable that uses the name of a function, you sometimes get unexpected results. Check whether a proposed...

However, the same call usingallow-empty=truethrows an error. Defining the name-value argument in an arguments block ensures that the names you define are valid MATLAB variable names and compatible with thename=valuesyntax. Avoiding Unexpected Results with Text Inputs Functions that include both opt...
For System 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. ...
Variable name, given variable numberSyntax name = cdflib.getVarName(cdfId,varNum) Description name = cdflib.getVarName(cdfId,varNum) returns the name of the variable in a Common Data Format (CDF) file. cdfId identifies the CDF file. varNum is a numeric value that identifies the variable....
y = ampl.getVariable('y'); x2 = x.get(2); y2_2 = y.get({2,2}); x2.fix(3); y2_2.fix(4.4); x.display y.display 给出: ans = x [*] := 1 0 2 3 3 0 4 0 5 0 ; ans = y := 1 1 0 1 2 0 2 1 0 ...
classmethod Variable.getValues() 用法 df = v.getValues() df = v.getValues(suffixes) 說明 這些函數返回一個數據幀,其中包含變量的所有指定值,與底層 AMPL 分離。要訪問數據,請參閱 DataFrame 。 v.getValues() 獲取AMPL 值(相當於後綴 val ) v.getValues(suffixes) 允許用戶指定要獲取的後綴 輸入參數 ...
function getname(a,b) s = inputname(1); disp(['First calling variable is ''' s '''.']) end Call the function at the command prompt using the variables x and y. Get x = 5; y = 3; getname(x,y) First calling variable is 'x'. Call the function using values instead of...
Instead, assign the handle to a variable, then use the variable name to specify the block. In this example, the value is assigned to the variable named h. Get num = get_param(h,'Numerator') num = '[1]' Get denom = get_param(h,'Denominator') denom = '[Tal,1]' Get ...
