Hi, I want to dimensionaly reduce the data set in Excel file. I converted data set in Excel file to .mat file. Now i want to use this for dimensionlity reduction. How can i use this file... i tried to find intrinsic dimensionality then it showed following error: >> whos Name Size Bytes Class Attributes
num 200x5 8000 double
raw 200x5 68000 cell
txt 0x0 0 cell
>> d= intrinsic_dim('C:\Users\lenovo\Desktop\xl.mat', 'MLE'); ??? Index exceeds matrix dimensions.
Error in ==> intrinsic_dim at 218 knnmatrix= .5 * log(distance(2:k2 + 1,:));
Can u tel me what m i missing... Thanks in advance.

I think you need to pass the matrix and not the file it self to the function:
Try the following with you matrix data:
d= intrinsic_dim(num, 'MLE');
