The ability to directly import DIAdem TDMATLAB files is not available in MATLAB.
To work around this issue, you can use the "loadlibrary" function as demonstrated in the following example from National Instruments™:
Reading TDM/TDMS Files with MathWorks, Inc. MATLAB® Software

You can also export the measurement data from DIAdem into MS Excel or as an ASCII-formatted text file, and then import the data into MATLAB. Note that MS Excel is limited to 2^16 (65,536) rows for older versions and 2^20 (1,048,576) rows for newer versions.
To import Excel data into MATLAB you can use the "xlsread" command. The best function to use depends on the format of the text file. Several possible options are "csvread", "dlmread" or "textscan".
For more information on each of these commands please execute one of the commands below at the MATLAB command prompt:
doc xlsread
doc csvread
doc dlmread
doc textscan
