I am attempting to plot a periodogram in Swift of a signal using Surge.

Code:

var fft_mat = Surge.pow(Surge.fft(signal), 2)
var const_mult = 2.0/Double(signal.count)
for var i in 0..<fft_mat.count { //multiply fft_mat by const_mult
    fft_mat[i] = Float(const_mult) * fft_mat[i]
}
var pgram = fft_mat

Plotting pgram yields the following results

For now only strings are accepted as the measures parameter in GridSearchCV, RandomizedSearchCV, and cross_validate. It's thus impossible to use those with measures that take specific parameters as input (e.g. #156 ), or to use custom measures.

We should then accept callables in addition to strings.

Each callable should only take the predictions parameter. In order to handle measur

Could you give me an example of how to use/run any of the algorithms under the superclass of factorization machine recommender?
An example of the format of the data, main parameters, anything would help.
The documentation isn't clear enough for me.

Brent.TryFindRoot and Bisection.TryFindRoot both allow a caller to pass in a negative value for the accuracy (arguably 0 could also be problematic, but should probably be permissible). However, the implementation of each means that it never considers itself to be within the requested accuracy, therefore always returns false.

Given that an accuracy is an absolute value, ideally the caller is eit

The current implementation of PartialEq for Matrix only works between two instances of the exact same type. We should extend it to allow comparison of matrices that have different types (owned vs sliced, static vs dynamic shapes etc.), but represent the same matrix, in a mathematical sense.

Moreover, the current implementation of PartialEq panics when the sizes of the matrices don't match

The ObjectMatrix is a matrix made up of objects which implement the ObjectArithmetic interface. The Matrix class itself has add(), subtract() and multiply() functions, so it implements these functions. In theory, we should be able to add implements ObjectArithmetic to the Matrix class, create an ObjectMatrix of a few distinct matrices and verify that the BlockMatrix axioms function as expected.

I am submitting a Feature Request

Lack of description of the "-l" lock option in the man page.
The option is proposed when you type "cmatrix -h" to get help text, but anything in man page.

Request :
Complete the man page (and add the manner to quit this lock screen.)
Or suppress this option that force you to reboot if you don't know how to "unlock"

What do you think to have some statistical tests like: Wilcoxon, t-student, etc in order to evaluate classifiers between different runs on the same dataset?

In the Linalg module in owl-base, several functions can only be applied to float input type. They should be extended to accept complex ndarrays. The unittest should also be updated accordingly.

I realised that if we change the value of err in a defer statement, we are effectively overwriting the result of tmpFile.Close() to err which could be non-nil. This behaviour is triggered only for named return values.

For instance, if the deferred function is a fu

These methods are quite useful whenever you have to make sure that a value stays inside a specified range. Although there is f32::clamp and f64::clamp these are not stabilized yet so it would be nice to have them inside cgmath.

wraparound should have a signature like this:

fn wraparound<S>(x: S, min: S, max: S) -> S

• Do we want to change glm_vec_ namespace to glm_vec3_?
• I want to rename glm_vec_flipsign() to glm_vec_negate() and deprecate glm_vec_flipsign() in favor of negate
• glm_vec_inv() inverts sign of components (same as negate) but probably it should invert vector components like glMatrix.js (https://github.com/toji/gl-matrix/blob/master/src/vec3.js#L321)? :

• Proposal

Using DocFX, it’s possible to automatically get a documentation website that is in synced with the source implementation. A good use case for this proposal is to quickly check the differences between the math library here and the one located in opentk.

Alternatives

None at the time.

All functions, macros and datatypes defined by cranium should have a prefix associated with them to avoid having cranium and another library's defined functions conflict during compilation.

For example, you defined MAX in FUNCTION_H, which may conflict with a differently defined MAX from another projects headers. Instead CRANIUM_MAX(...) should be used. You may want to do this with your templat
