Simple question about checking if a variable exists. I want my function to check if a given parameter exists in the workspace before attempting to modify it. If it doesn't exist, my function should behave differently. Something like this: ...
%disp(testresults); %can't work because variable testresults does not %exist. testresults = magic(5) %create variable exist testresults; %returns "1", variable exists if (exist testresults var) %why can't I check if this exists? %File: temp.m Line: 6 Column: 11...

2、1、Suppose there exists the A^{-1}\in \Re^{m\times m} such that AA^{-1}=A^{-1}A=I 3、The variable x is: x=A^{-1}b (十五)Inverse Matrix(逆矩阵) 1、For a matrix A,the inverse is defined as: where det( A)is the determinant: det( A)=|ad-bc| 2、Properties:...
exists in the connected data source. If a data connection can access multiple data sources (for example, a data dictionary and its referenced dictionaries), the function returns 1 (true) if the variable exists in any of the visible data sources. ...

This assigns the string Male to variable. For large amounts of data, perhaps saved in a previous Matlab session, the function load allows the loading of files from disk using load filename The filename normally ends in .mat or .dat. A file of sunspot data already exists in the Matlab...
