Selects elements from the source operands src0 and src1 based on the bit values of the mask to produce the destination operand dst. The selection rule is: when the mask bit is 1, the element at the corresponding position is selected from src0; when the mask bit is 0, the element at the corresponding position is selected from src1.

The calculation formula is as follows:

$$dst_i = (mask_i == 1) ? src0_i : src1_i$$ [object Object][object Object][object Object]undefined
