Easy Split Bill vs n Matrix Calculator

It is a free app that makes it easy to calculate split bills. You can calculate the payment amount per person from the payment amount and the number of people. You can set the unit for rounding the amount to 1 $ or 10 $, and set whether to change the fraction or pay by one person. Split bill calculation The split bill is calculated from the payment amount, number of people, unit, and division method. You can choose whether or not to set conditions for some people, and you can set conditions. You can fix the amount of money for some people, make a difference by amount, make a difference by percentage, and so on. Easy split bill calculation (only amount and number of people) You can easily calculate the split bill from the amount of money and the number of people. The unit for rounding the amount varies depending on the amount paid per person. Easy split bill calculation (separate by gender) You can calculate the per capita payment for men and women from the payment amount and the number of men and women. It can be used when you want to divide the conditions in a joint party or two groups. Easy split bill calculation (one secretary) You can calculate the split bill when there is only one secretary from the payment amount and the number of people. You can change the conditions of the secretary in various ways. Divide the split bill by percentage You can calculate the payment amount per person from the payment amount, the number of people and the ratio of the payment. You can create as many groups of people and percentages as you like. You can also change the rounding method. Please note that if the unit for rounding the amount is large, and if there is a difference in the amount, the rounding process may not reflect the conditions at all.

Application Functions 1. Calculation for a single matrix Find determinant, inverse matrix, eigenvalues, and eigenvectors of any square matrix. 2. Matrix calculation using expression Input any square matrix to A, B, C, and D, respectively, and calculate values based on mathematical expressions such as (8A-6B)*1C+9D 3. Calculation of simultaneous equations Calculates simultaneous equations expressed in matrix form as Ax = b, where A is a square matrix and b is a vertical vector. Features of the application 1. All functions support complex numbers. Complex matrices, eigenvalues and eigenvectors are supported even when they are complex numbers. 2. Arbitrary square matrices can be calculated. Supports not only basic matrices such as 2 x 2 and 3 x 3, but also high-dimensional matrices such as 100 x 100. 3. Copy and paste from spreadsheet software Calculations can be performed by copying and pasting cells from spreadsheets such as Excel and Numbers. Please be careful of line breaks after pasting. 4. Fast calculation speed Even for a 100 x 100 matrix, determinant, inverse matrix, rank, eigenvalue, and eigenvector can be calculated in only 1 second. 5. Can be used offline You can perform matrix calculations anytime, anywhere. How to use 1. In case of inputting an actual matrix or CSV Use newlines and commas to represent matrices as follows. 2,6,7 8,11,3.5 65,3,11 Please do not include spaces. 2. In case of executable matrix and Space input Use line breaks and commas to represent matrices as follows 2 6 7 8 11 3.5 65 3 11 This input method allows you to copy and paste spreadsheet cells Do not include more than two spaces. 3. For complex matrix and CSV input Use line breaks and commas to represent matrices as follows 1+2i,-3i 4,0 Please do not include spaces. Please add coefficients, even if they are i or -i i → 1i -i → -1i 4. For complex matrix and Space input Use line breaks and commas to represent matrices as follows 1+2i -3i 4 0 Do not put more than two spaces. Please add a coefficient, even if it is i or -i i → 1i -i → -1i
