inputname(argnum) returns the workspace variable name corresponding to the argument number argnum. If the input argument has no name (for example, if it is an expression instead of a variable), the inputname command returns the empty string (”)
% Set the Fibonacci number to calculate.% Create a row vector called containing n ones. F = ones(1,n); % This vector is used to store the Fibonacci % numbers; its first element is currently F_1 % and its second element is F_2 (if n>1).%...
This MATLAB function constructs a string or character vector varname that is similar to or the same as the str input, and can be used as a valid variable name.
IfmyFuncaccepts a variable number of input arguments, then process all the arguments specified byvarargin. function y = myFunc(varargin) [varargin{:}] = convertCharsToStrings(varargin{:}); ... TheconvertCharsToStringsfunction is more efficient when converting one input argument. If performance is ...

Regular expressions that define the variables to display, specified as one or more character vectors or string scalars. For example,who -regexp ^Mon ^Tueslists only the variable names in the workspace that begin withMonorTues. For more information about creating regular expressions, seeRegular Exp...
Example:T2 = convertvars(T1,'Region','categorical')converts the type of the variableRegion. Example:T2 = convertvars(T1,[1,3:6],'string')converts variables specified by position to string arrays. Example:T2 = convertvars(T1,@isnumeric,'int32')converts all numeric variables to 32-bit ...
Undefined function or variable 'x'. 具体原因可以参考第1节匿名函数的调用。 但是fzero不支持syms类型的函数,如下的代码会报错 syms a b c x; f4 = a*x^2 + b*x + c; f4 = subs(f4, {a, b, c}, {1, 4, 1}); x4 = fzero(f4, -2 - sqrt(3)) ...
A testsuite is available when building with the GNU autotools. To run the testsuite, first configure and build matio. After building runmake checkto run the testsuite. If matio was built without zlib, the compressed variable tests will be skipped. If built without HDF5, the tests for version...
