Hallo, I have 3-axis accelerometer and 3-axis gyroscope, I am planning to reduce these 6 axis to only one or two significant axis that gives more details than others by using PCA

Hi,
As per my understanding, you want to use Principle Component Analysis (PCA) to reduce the dimensionality of your dataset from 6 to 1 or 2 dimensions.
To perform PCA, you can use MATLAB command ‘pca’, which calculates the principal component coefficients for the dataset. You can also specify the number of components to return by using argument ‘NumComponents’.
Assume that the data is stored in variable ‘X’.
[coeff, score] = pca(X, 'NumComponents', 2);
‘coeffs’ are the principal component coefficients, and ‘score’ is the dataset in reduced dimension as specified by the ‘NumComponents’ argument.
For more information on 'pca' command, you can visit the documentation page: https://in.mathworks.com/help/stats/pca.html
Hope this resolves the issue.
