Functions

Name	Brief	Example
find_largest_gap	get the index of largest gap from value array, array must be sorted first	Examples
ocmath_b_copy	Copy a vector of type BYTE with given array of indices.	Examples
ocmath_check_order	Check a segment of curve's X value is monotonic increase, monotonic decrease, or not monotonic.	Examples
ocmath_compare_data	Compare two vectors or matrices cell by cell in predefined tolerance.	Examples
ocmath_d_copy	Copy a vector of type double with given array of indices.	Examples
ocmath_d_get_vector_inc	Check data monotonic increasing or decreasing with consistant increment or otherwise.	Examples
ocmath_d_stretch	Stretch (or squeeze) data in a vector or a matrix of type double by scaling all the data within a given range.	Examples
ocmath_f_copy	Copy a vector of type float with given array of indices.	Examples
ocmath_f_stretch	Stretch (or squeeze) data in a vector or a matrix of type double by scaling all the data within a given range.	Examples
ocmath_group_xy_by_x	This function separates XY data to groups according to their X values.	Examples
ocmath_i_get_vector_inc	Check data monotonic increasing or decreasing with consistant increment or otherwise.	Examples
ocmath_is_monotonic	Judge if a vector is (strictly) monotonic. Call the function IsOrdered of class NRVec to check the vector in (strictly) ascending(descending) order or not.	Examples
ocmath_linear_transform	Map data array slope [min, max] to [nMin, nMax] linearly	Examples
ocmath_replace_data_in_vector	Replace elements that match the condition in a vector	Examples
ocmath_simple_math	Perform arithmatic operation element-wised on two curves	Examples
ocmath_sort_xy	sort two double arrays with X sorted and Y to reorder accordingly	Examples
ocmath_ui_copy	Copy a vector of type UINT with given array of indices.	Examples
ocmath_us_copy	Copy a vector of type USHORT with given array of indices.	Examples
ocmath_us_stretch	Stretch (or squeeze) data in a vector or a matrix of type double by scaling all the data within a given range.	Examples
ocmath_xyzv_remove_duplicates	This function remove duplicated points and replace duplicated points by nMethod, where 0 means replace with mean, 1=median, 2=min, 3=max, 4=sum	Examples
vec_is_equal	Check if all elements in vector are equal	Examples
