The function uses p_array=strsplit(path(),pathsep) to create the cell array, and then any(strcmp(p_array,folder_to_search_for)) to check if the folder you're looking for is in the cell array. Not sure if it's slower/faster than the regexp approach for a large number of folders, but I find it conceptually simpler.įirst, create a function for checking a single path. Old question, but here's another way using cell arrays by splitting the path() string. %%// strjoin is a recent MATLAB addition and is also available on file-exchange. Ind1 = ismember(basepath_list_cell,path_list_cell)Īddpath(strjoin(strcat(basepath_list_cell(~ind1),pathsep),'')) %%// basepath1 is the path to the main directory with sub-directories thatīasepath_to_be_searched = genpath(basepath1)īasepath_list_cell = regexp(basepath_to_be_searched,pathsep,'Split')īasepath_list_cell = regexp(path,pathsep,'Split') So even if you have selectively removed any sub-directory or even the basepath from the path, this code would take care of adding everything that's missing from the path. Main directory along with sub-directories search case with adding optionįor a basepath alongwith sub-directory search, the following code would try to find match for each sub-directory and also the basepath and add which ever is missing. If any(ismember(path_to_be_searched,path_list_cell))ĭisp('Yes, this directory is in MATLAB path') ĭisp('No, this directory is not in MATLAB path') Path_list_cell = regexp(path,pathsep,'Split') ![]() %%// For Windows and others, it needs to be investigated. %%// colon is the separator used for paths under Linux. To use this function with MATLAB, you need to apply MATLAB's MEX compiler.if you have never used the MEX compiler before, you may have some difficulty, since you need to determine that you have the MEX compiler, that you have a C or C++ compiler on your system, that MEX knows where these compilers are, and that you know how to invoke MEX to compile the function.Single directory search case %%// path_to_be_searched is the folder or directory to be detected It does not require that the triangulation be Delaunay. One alternative is a file called tsearch_mex.c, which searches a triangulation to determine which triangle contains each point. Therefore, the call to tsearch() also causes MESH2D to fail! The tsearch() function has since been removed from MATLAB. The MESH2D function "mytsearch()" was originally written to call MATLAB's "tsearch()" function. To see the power of having your investments compound tax-free, let's imagine someone invests 500 monthly and averages 8 annual returns over 30 years. (I believe it is intended to generate a "wait bar", similar to the hourglass or beachball or wristwatch icons. Easily save thousands in capital gains taxes. ![]() The call to this function fails on my system, and since it seems to have no importance whatsoever, I commented it out. row,col find ( ) returns the row and column subscripts of each nonzero element in array X using any of the input arguments in previous syntaxes. The MESH2D routines include a call to a function called wbar(). This copy is essentially my personal working copy, to which I may have added comments, small coding changes, and extra tests and examples. Interested users should refer to the copy of MESH2D that is made available through the MATLAB Central File Exchange. ![]() The program relies heavily on the features of the Delaunay triangulation, which chooses, among all possible triangulations of a set of points, that triangulation which best avoids small angles. The density of the triangular mesh can be uniform, or the user can request that smaller triangles be used near certain features of the region. MESH2D is most useful because it allows a user to specify a shape or region, which the program will then fill with a triangular mesh. The user is able to define a variety of geometric shapes, and desired mesh densities. MATLAB uses the search path to locate files used with MathWorks ® products efficiently. The code is relatively simple, flexible and powerful. What Is the MATLAB Search Path The MATLAB ® search path is a subset of all the folders in the file system.
