Matlab trace format files contain spectra series in a 2D data format where the first dimension is the spectral dimension and the second dimension represents the perturbing variable, i.e. time, pressure, temperature, spatial dimension, etc. 

To load Matlab trace files select ''Load Data'' → ''Matlab trace format'' → ''x-data'', or ''y-data'' from the ''Load Data'' menu bar.

Matlab trace files contain five different variables to store the spectral data as well as relevant metadata: 
* ''spc'' – this variable contains the spectral data, a 2D array of double precision floating point values (float32). Columns indicate individual spectra of absorbance, intensity, transmittance, etc. values. The column length indicates the number of data points per spectrum. The number of columns is equal to the number of observations i.e. the number of spectra.
* ''tos'' - A character vector of variable length which indicates the type of spectra. Examples are ''Transmission'', ''Fluorescence'', ''Raman'', etc.
* ''vst'' - A character vector of variable length indicating the type of the perturbing variable. Examples of vst: ''Temperature'', ''Time'', ''Voltage'', ''Pressure'', or ''Spatial variable''.
* ''war'' - A vector of float32 values with the perturbing variable: ''temperature'', ''time'', ''voltage'', ''pressure'', etc. The length of ''war'' must be equal to size(spc,2).
* ''wav'' - A vector of float32 values, the ''wavenumber'' vector, or more general the vector of y-values (frequencies, wavenumbers, Raman shift. wavelength, or alternative variables). The length of ''wav'' must equal the number of data points per spectrum, i.e. size(wav,1) == size(spc,1). Equidistancy of the 'wav' vector is not a requirement.
