Data sets covers the shear strengths from geosynthetics
a numeric for the cohesion, in kPa
a numeric for the inner friction angle, in degree
The data set contains several columns : cohesion, friction angle, unit grivity, investigator, published year, rock name.
Returns a matrix that contains above values for each GCL included in the data set.
